For exam-ple, clicking the TC Electronic logo in the upperleft corner of each page will take you to the tableof contents.To get the most from this manual, please read itfrom start to finish, or you may miss importantinformation.To download the most current version of thismanual, visit /support/manuals/Enjoy your TC product!Introduction Introduction“Size matters not. Look at me.Judge me by my size, do you?”Yoda(“Star Wars: Episode V –The Empire Strikes Back”)Congratulations on your purchase ofTC Electronic’s amazing Spark Mini Booster!Never judge a book by its cover –or a booster pedal by its size.Spark Mini Booster was designed by musiciansfor musicians to give you an amazing extra toolfor your musical tool box. It’s an extremely ver-satile pedal that will help you get better sounds.The possibilities with Spark Mini Booster are vir-tually endless:– Leave it on all the time,– punch it in from time to time when you needa volume boostor– put it in front of your favorite overdrive / dis-tortion pedal to add more tonal options toyour existing pedal board.The choice is yours!Ready for PrimeTime?PrimeTime™ is a radical new feature that willexcite guitarists around the globe. Spark MiniBooster instantly understands whether you wantthe pedal to be permanently on when you hit thefootswitch, or just for as long as you hold thefootswitch down. Which totally rocks for both“always-on” and “emphasizing passages” situ-ations.Se tup SetupReady…The Spark Mini Booster box should contain the following items:– 1 Spark Mini Booster pedal– 2 rubber feet for “non-velcro” pedalboard mounting– 1 TC Electronic sticker– 1 leaflet about TC’s guitar FX product range.Inspect all items for signs of transit damage. In the unlikely event of transit damage, inform the carrier and supplier.If damage has occurred, keep all packaging as it can be used as evidence of excessive handling force.Set…– Connect a 9 V power supply with the followingsymbol to the DC input socket of Spark MiniBooster.! Spark Mini Booster does not come with apower supply.– Plug the power supply into a power outlet.!Please note that Spark Mini Booster has nobattery compartment. A conventional powersupply is required for operating this product.– Connect your instrument to the I NPUT jackon the right side of the pedal using a ¼“ jackcable.– Connect the OUTPUT jack on the left side ofthe pedal to your amplifier using a ¼“ jack ca-ble.Play!Inputs, output, controlsInputs, output, controls1. Power input This is a standard 5.5 /2.1 mm DC plug (centre = negative). To power up Spark Mini Booster, con-nect a power supply to its power input socket. Spark Mini Booster requires a 9 V power supply providing 40 mA or more (not supplied).To minimize hum, use a power supply with iso-lated outputs.2. Audio input This is a standard ¼“ input jack (mono / TS).Connect your guitar here using a regular ¼“ mono cable.For other setups, see the “Setup examples” sec-tion of this manual.3. Audio output This is a standard ¼“ output jack (mono / TS).Connect this jack to your amplifier using a regu-lar ¼“ mono cable.For other setups, see the “Setup examples” sec-tion of this manual.4. Level knob Use this knob to control the level change when the booster is enabled.Minimum setting will leave the level of your signal unchanged while the maximum setting will give you 20 dBs of boost.5. Footswitch Using the footswitch as a standard on / off switch To turn the pedal on, tap the pedal’s footswitch briefly. To turn the pedal off, tap the footswitch again. This works as with any other pedal on your board.PrimeTime Use the PrimeTime feature for brief solos and licks that last only for a few seconds.To engage PrimeTime, hold down the pedal’s footswitch. To disengage, release the footswitch.During PrimeTime, boost will be on. As soon as you release the footswitch, boost will turn off again.Working with a booster: setup examples Working with a booster:setup examplesSpark Mini Booster is an awesome and versatile tool that can be used in more ways than just one.1. Punch it in from time to time when you need a volume boost.2. Punch it in from time to time when you need a gain boost.3. Leave it on all the time to get the best out of your tube amp.Understanding the difference between sce-narios 1 and 2 is essential when working with Spark Mini Booster.When playing with a distortion pedal or an over-driven amp, you know how turning down the vol-ume knob on your guitar cleans up your guitar sound?Well – guess what happens if you do the oppo-site and turn up your signal even more with the booster? Right: more drive is what happens! Refer to whichever scenario fits your require-ments:“I want a volume boost!”Awesome! Then you want to place Spark MiniBooster after your distortion pedal(s).If you use pedals for your distortion sounds, thenyou will want to place your Spark Mini Boosterdirectly after those pedals.I f you use the distortion of your amplifier, thenyou’ll need to place Spark Mini Booster in the FXloop of your amp – otherwise you’ll end up with again boost as explained in the following section.“I want a gain boost!”Rock on! Place Spark Mini Booster before yourdrive pedals or distorting amp to use it as an ex-tra gain switch for increased gain and sustain. Ifyou set up Spark Mini Booster this way, you canuse it to lift the volume of your clean sound whendrive is disengaged. In other words: If used cor-rectly, this can transform an awesome soundingsingle-channel amp into a ridiculously awesomesounding two-channel amp!“Wait – there’s more!?”“Yep. Always on!”I n many configurations, driving your amp a bitharder can give you better tone. So try leavingSpark Mini Booster on all the time – and youmight find yourself addicted and wanting an ex-tra Spark Mini Booster…Setup examples Setup examplesUsing Spark Mini Booster as a volume boosterModulation, delay &reverb pedalsUsing Spark Mini Booster as a gain boosterModulation, delay &reverb pedalsDrivepedalsUsing Spark Mini Booster in an FX loopFX Loop Send ►Frequently asked questionsThe sound of silence: True BypassHere at TC, we have a simply philosophy: When you are using one of our products, you should hear something great – and if you don’t, you shouldn’t hear it at all. This is why this pedal sports True Bypass. When it is bypassed, it is really off and has zero influence on your tone, resulting in optimum clarity and zero loss of high-end.Frequently asked questions“What are the input / output impedance val-ues for Spark Mini Booster?”Input Impedance is 1 MΩ. Output Impedance is 100 Ω.“Is Spark Mini Booster analog or digital?”The entire signal path of Spark Mini Booster is 100 % analog.“Should I place my Spark Booster in front of the amp, or is it better to run it in the amp’s FX loop?”The placement really depends on what you are looking for. f you place it in front of the amp, the Spark Booster will boost the pre-amp signal in your amp and create a more overdriven sound. I f you put it in the loop, you will boost the volume of your amp as the ped-al will be placed after the pre-amp section. Check out the section of this manual called Working with a booster / Setup examples.“Does Spark Mini Booster have balanced or unbalanced input / output?”Spark Mini Booster has unbalanced I / Os. Use cables with TS jack – i.e., standard instrument cables.Getting supportTechnical Specifications – Maximum Setting: 20 dB– Minimum Setting: 0 dB boost (unity gain)– Bypass mode: True Bypass– Signal Circuitry: 100 % analog– Dimensions (Width x Depth x Height):48 x 48 x 93 mm / 1.9 x 1.9 x 3.7“– Input Connector Type:Standard ¼“ jack – mono / TS– Output Connector Type:Standard ¼“ jack – mono / TS– Power Input:Standard 9 V DC,centre negative> 40 mA (not supplied)Due to continuous development, these speci-fications are subject to change without no-tice.Controls– Level Knob: Amount of boost– Switch: Boost On / off / PrimeTime– PrimeTime:Holding down the footswitch for more than one second will activate PrimeTime for boos-ting essential passages.

当然也有其他的选择。
Openfire是基于Jabber协议(XMPP)实现的即时通信服务器端版本,目前建议使用3.6.4版本,这个版本是当前最新的版本,而且网上可以找到下载的源代码。
即时通信客户端可使用spark2.5.8,这个版本是目前最新的release版本,经过测试发现上一版本在视频支持,msn网关支持上可能有问题,所以选择openfire3.6.4+spark2.5.8是最合适的选择。
Smack是即时通信客户端编程库,目前我已测通通过jsp使用smack的API向openfire 注册用户发送消息,并且可以通过监听器获得此用户的应答消息。
通过smack向msn用户和QQ用户,gtalk用户发送消息应该也可以实现,关于向gtalk 用户发送消息的例子较多。
这个留待以后研究。
至少目前可以通过程序向spark发消息了。
对于局域网内部应用足以解决系统与用户交互的问题,甚至可以做自动应答机器人。

1.引言本文档描述一个生产型hadoop和spark集群的安装、配置过程。
设置单机部署在相应步骤中有描述,可参考。
2.软件包和版本OS: SLES12 SP3Anaconda3-5.0.1-Linux-x86_64.shapache-flume-1.8.0-bin.tar.gzhadoop-2.7.5.tar.gzhadoop-3.0.0.tar.gzjdk-8u152-linux-x64.tar.gzkafka_2.12-1.0.0.tgzspark-2.2.1-bin-hadoop2.7.tgz全部复制到/root/software目录下。
3.集群规范推荐硬件配置:处理器:2个6核或8核,主频3GHz内存:64-512 GB ECC存储器:12-24块1-4TB SATA网络:带链路聚合的千兆以太网RAID:Namenode可以使用以保护元数据Datanode 依靠JBOD技术,据说比RAID强集群规模:一般认为10个节点算小集群入门规模,咱先按照4台安装,分开部署master,分开部署主namenode和辅助 namenode网络拓扑:推荐一个机架(rack)安装30-40台服务器,共享1个10GB交换机;各机架间的交换机通过上行链路与核心交换机或路由器互联(至少10GB);同一机架内节点之间的总带宽远高于不同机架间的带宽。
4.创建linux用户账号HDFS、mapreduce、yarn通常使用独立用户运行,分别命名为hdfs、mapred、yarn,同属于hadoop组。
5.安装javawiki上介绍的java版本都太老了,直接使用jdk8最新版本安装,统一安装在/opt下:cd ~/softwaretar zxf jdk-8u152-linux-x64.tar.gzmv jdk1.8.0_152/ /opt编辑/etc/profile,在文件最后添加:## JAVA setting#export JAVA_HOME=/opt/jdk1.8.0_152export PATH=$JAVA_HOME/bin:$PATHexport CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar 执行source /etc/profile6.s sh配置应允许集群内机器的hdfs和yarn用户无需密码登录:su - hdfsssh-keygen -t rsa -f ~/.ssh/id_rsassh-copy-id -i ~/.ssh/id_rsa.pub hadoop-1exitsu - yarnssh-keygen -t rsa -f ~/.ssh/id_rsassh-copy-id -i ~/.ssh/id_rsa.pub hadoop-1或者在第一台服务器配置好后,将/home作为nfs导出,其他服务器将其mount到本地/home下,再ssh一下新服务器即可。
7.安装hadoopcd ~/software/tar zxf hadoop-3.0.0.tar.gzchown -R hdfs:hadoop hadoop-3.0.0/mv hadoop-3.0.0 /opt/cd /opt/hadoop-3.0.0/mkdir logschmod 777 logs编辑/etc/profile,在文件最后添加:## HADOOP setting#export HADOOP_HOME=/opt/hadoop-3.0.0export PATH=$PATH:$HADOOP_HOME/bin:$HADOOP_HOME/sbin执行source /etc/profile8.格式化HDFS文件系统全新的hdfs安装需要格式化,创建存储目录和初始化namenode:su - hdfshdfs namenode -format9.H ADOOP配置各重要配置文件的配置项目及解释:core-site.xml:<configuration><property><name>fs.defaultFS</name><value>hdfs://hadoop-1/</value></property><property><name>io.file.buffer.size</name><value>131072</value></property></configuration>①将一台机器指定为namenode,fs.defaultFS属性描述hdfs文件系统的URI,端口默认是8020。
hdfs-site.xml:<configuration><property><name>.dir</name><value>file:/namenode/hdfs/name,file:/nfs/hdfs/name</value></property><property><name>dfs.datanode.data.dir</name><value> file:/datanode/hdfs/data1, file:/datanode/hdfs/data2</value></property><property><name>node.checkpoint.dir</name><value> file:/namenode/hdfs/namesecondary</value></property><property><name>dfs.client.read.shortcircuit</name><value>true</value></property><property><name>dfs.domain.socket.path</name><value> file:/var/run/hadoop-hdfs/dn_socket</value></property></configuration>①.dir用来存储永久性的文件系统元数据(编辑日志和文件系统映像),这些元数据文件同时保存在所有目录中,可以将元数据写到一两个本地磁盘和一个远程磁盘上(辅助namenode只定期保存检查点,不维护最新元数据)。
默认值是file://${hadoop.tmp.dir}/dfs/name。
②dfs.datanode.data.dir设定datanode存储数据块的目录列表,可指定一系列目录使其在各目录循环写入,因此建议为每块本地硬盘指定一存储目录,跨磁盘分布数据块可以提升读取性能(设置noatime选项挂载分区,不会刷新文件最近读取时间,显著提升性能)。
默认值是file://${hadoop.tmp.dir}/dfs/data。
③node.checkpoint.dir指定辅助namenode存储检查点的目录,可以指定一系列目录,数据文件同时保存在所有目录中,以实现冗余备份。
默认值是file://${hadoop.tmp.dir}/dfs/namesecondary。
④${hadoop.tmp.dir}默认是/tmp/hadoop下。
yarn-site.xml:<configuration><property><name>yarn.resourcemanager.hostname</name><value>hadoop-2</value></property><property><name>yarn.nodemanager.local-dirs</name><value>file:/datanode/hdfs/local-dir1,/datanode/hdfs/local-dir2</value></property><property><name>yarn.nodemanager.aux-services</name><value>mapreduce.shuffle</value></property><property><name>yarn.nodemanager.resource.memory-mb</name><value>24576</value></property><property><name>yarn.nodemanager.resource.cpu-vcores</name><value>40</value></property></configuration>①yarn.resourcemanager.hostname为运行资源管理器的主机名或IP地址。
在mapreduce客户端配置中,需要通过rpc连接资源管理器时,会用到这个属性。
②yarn.nodemanager.local-dirs为yarn容器本地临时存储空间,包括map任务的输出数据都会写到这里,因此要求尽量大,指定一系列目录使其在各目录循环写入,提升IO性能。
通常情况下,yarn本地存储会使用与datanode相同的分区。
③yarn依赖于shuffle句柄将map任务输出给reduce任务。
shuffle句柄是长期运行于节点管理器的附加服务。
因为yarn是通用目的服务,因此要通过将yarn-site.xml中的yarn.nodemanager.aux-services属性设为mapreduce.shuffle以显式启用mapreduce的shuffle句柄。
④yarn.nodemanager.resource.memory-mb节点管理器运行容器可分配的物理内存。
一个运行容器的节点管理器分配的内存取决于机器的物理内存,每个hadoop守护进程约用1000MB内存,因此每个节点运行1个节点管理器和1个datanode共需2000MB内存。
