1.部署环境
2.Spark集群规划
3.建立ssh
cd ~ #生成公钥和私钥 ssh-keygen -q -t rsa -N "" -f /home/ebupt/.ssh/id_rsa cd .ssh cat id_rsa.pub > authorized_keys chmod go-wx authorized_keys #把文件authorized_keys复制到所有子节点的/home/ebupt/.ssh目录下 scp ~/.ssh/authorized_keys ebupt@eb175:~/.ssh/ scp ~/.ssh/authorized_keys ebupt@eb176:~/.ssh/
另一个简单的方法:
由于实验室集群eb170可以ssh到所有的机器,因此直接拷贝eb170的~/.ssh/所有文件到eb174的~/.ssh/中。这样做的好处是不破坏原有的eb170的ssh免登陆。
[ebupt@eb174 ~]$rm ~/.ssh/* [ebupt@eb170 ~]$scp -r ~/.ssh/ ebupt@eb174:~/.ssh/
4.部署scala,完全拷贝到所有节点
tar zxvf scala-2.11.2.tgz
ln -s /home/ebupt/eb/scala-2.11.2 ~/scala
vi ~/.bash_profile
#添加环境变量 export SCALA_HOME=$HOME/scala export PATH=$PATH:$SCALA_HOME/bin
通过scala –version便可以查看到当前的scala版本,说明scala安装成功。
[ebupt@eb174 ~]$ scala -version
Scala code runner version 2.11.2 -- Copyright 2002-2013, LAMP/EPFL
5.安装spark,完全拷贝到所有节点
解压建立软连接,配置环境变量,略。
[ebupt@eb174 ~]$ vi spark/conf/slaves
#add the slaves
eb174
eb175
eb176
[ebupt@eb174 ~]$ vi spark/conf/spark-env.sh
export SCALA_HOME=/home/ebupt/scala export JAVA_HOME=/home/ebupt/eb/jdk1.7.0_60 export SPARK_MASTER_IP=eb174 export SPARK_WORKER_MEMORY=4000m
6.安装shark,完全拷贝到所有节点
解压建立软连接,配置环境变量,略。
[ebupt@eb174 ~]$ vi shark/conf/shark-env.sh
export SPARK_MEM=1g # (Required) Set the master program‘s memory export SHARK_MASTER_MEM=1g # (Optional) Specify the location of Hive‘s configuration directory. By default, # Shark run scripts will point it to $SHARK_HOME/conf export HIVE_HOME=/home/ebupt/hive export HIVE_CONF_DIR="$HIVE_HOME/conf" # For running Shark in distributed mode, set the following: export HADOOP_HOME=/home/ebupt/hadoop export SPARK_HOME=/home/ebupt/spark export MASTER=spark://eb174:7077 # Only required if using Mesos: #export MESOS_NATIVE_LIBRARY=/usr/local/lib/libmesos.so source $SPARK_HOME/conf/spark-env.sh #LZO compression native lib export LD_LIBRARY_PATH=/home/ebupt/hadoop/share/hadoop/common # (Optional) Extra classpath export SPARK_LIBRARY_PATH=/home/ebupt/hadoop/lib/native # Java options # On EC2, change the local.dir to /mnt/tmp SPARK_JAVA_OPTS=" -Dspark.local.dir=/tmp " SPARK_JAVA_OPTS+="-Dspark.kryoserializer.buffer.mb=10 " SPARK_JAVA_OPTS+="-verbose:gc -XX:-PrintGCDetails -XX:+PrintGCTimeStamps " SPARK_JAVA_OPTS+="-XX:MaxPermSize=256m " SPARK_JAVA_OPTS+="-Dspark.cores.max=12 " export SPARK_JAVA_OPTS # (Optional) Tachyon Related Configuration #export TACHYON_MASTER="" # e.g. "localhost:19998" #export TACHYON_WAREHOUSE_PATH=/sharktables # Could be any valid path name export SCALA_HOME=/home/ebupt/scala export JAVA_HOME=/home/ebupt/eb/jdk1.7.0_60
7.同步到slaves的脚本
7.1 master(eb174)的~/.bash_profile
# .bash_profile # Get the aliases and functions if [ -f ~/.bashrc ]; then . ~/.bashrc fi # User specific environment and startup programs PATH=$PATH:$HOME/bin export PATH export JAVA_HOME=/home/ebupt/eb/jdk1.7.0_60 export PATH=$JAVA_HOME/bin:$PATH export CLASSPATH=.:$CLASSPATH:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar export HADOOP_HOME=$HOME/hadoop export PATH=$PATH:$HADOOP_HOME/bin:$HADOOP_HOME/sbin export ZOOKEEPER_HOME=$HOME/zookeeper export PATH=$ZOOKEEPER_HOME/bin:$PATH export HIVE_HOME=$HOME/hive export PATH=$HIVE_HOME/bin:$PATH export HBASE_HOME=$HOME/hbase export PATH=$PATH:$HBASE_HOME/bin export MAVEN_HOME=$HOME/eb/apache-maven-3.0.5 export PATH=$PATH:$MAVEN_HOME/bin export STORM_HOME=$HOME/storm export PATH=$PATH:$STORM_HOME/storm-yarn-master/bin:$STORM_HOME/storm-0.9.0-wip21/bin export SCALA_HOME=$HOME/scala export PATH=$PATH:$SCALA_HOME/bin export SPARK_HOME=$HOME/spark export PATH=$PATH:$SPARK_HOME/bin export SHARK_HOME=$HOME/shark export PATH=$PATH:$SHARK_HOME/bin
7.2 同步脚本:syncInstall.sh
scp -r /home/ebupt/eb/scala-2.11.2 ebupt@eb175:/home/ebupt/eb/ scp -r /home/ebupt/eb/scala-2.11.2 ebupt@eb176:/home/ebupt/eb/ scp -r /home/ebupt/eb/spark-1.0.2-bin-hadoop2 ebupt@eb175:/home/ebupt/eb/ scp -r /home/ebupt/eb/spark-1.0.2-bin-hadoop2 ebupt@eb176:/home/ebupt/eb/ scp -r /home/ebupt/eb/spark-0.9.1-bin-hadoop2 ebupt@eb175:/home/ebupt/eb/ scp -r /home/ebupt/eb/spark-0.9.1-bin-hadoop2 ebupt@eb176:/home/ebupt/eb/ scp ~/.bash_profile ebupt@eb175:~/ scp ~/.bash_profile ebupt@eb176:~/
7.3 配置脚本:build.sh
#!/bin/bash source ~/.bash_profile
ssh eb175 > /dev/null 2>&1 << eeooff ln -s /home/ebupt/eb/scala-2.11.2/ /home/ebupt/scala ln -s /home/ebupt/eb/spark-0.9.1-bin-hadoop2/ /home/ebupt/spark ln -s /home/ebupt/eb/shark-0.9.1-bin-hadoop2/ /home/ebupt/shark source ~/.bash_profile exit eeooff echo eb175 done!

8 遇到的问题及其解决办法
8.1 安装shark-0.9.1和spark-1.0.2时,运行shark shell,执行sql报错。

原因:不知道它在说什么,大概是说“protobuf”版本有问题.
解决:找到 jar 包 “hive-exec-0.11.0-shark-0.9.1.jar” 在$SHARK_HOME/lib_managed/jars/edu.berkeley.cs.shark/hive-exec, 删掉有关protobuf,重新打包,该报错不再有,脚本如下所示。
cd $SHARK_HOME/lib_managed/jars/edu.berkeley.cs.shark/hive-exec unzip hive-exec-0.11.0-shark-0.9.1.jar rm -f com/google/protobuf/* rm hive-exec-0.11.0-shark-0.9.1.jar zip -r hive-exec-0.11.0-shark-0.9.1.jar * rm -rf com hive-exec-log4j.properties javaewah/ javax/ javolution/ META-INF/ org/
8.2 安装shark-0.9.1和spark-1.0.2时,spark集群正常运行,跑一下简单的job也是可以的,但是shark的job始终出现Spark cluster looks dead, giving up. 在运行shark-shell(shark-withinfo )时,都会看到连接不上spark的master。报错类似如下:
shark> select * from t1;

FAILED: Execution Error, return code -101 from shark.execution.SparkTask
原因:网上有很多人遇到同样的问题,spark集群是好的,但是shark就是不能够很好的运行。查看shark-0.9.1的release发现
Release date: April 10, 2014
Shark 0.9.1 is a maintenance release that stabilizes 0.9.0, which bumps up Scala compatibility to 2.10.3 and Hive compliance to 0.11. The core dependencies for this version are:
Scala 2.10.3
Spark 0.9.1
AMPLab’s Hive 0.9.0
(Optional) Tachyon 0.4.1
这是因为shark版本只兼容到spark-0.9.1,版本不兼容导致无法找到spark集群的master服务。
解决:回退spark版本到spark-0.9.1,scala版本不用回退。回退后运行正常。
9.集群成功运行
9.1测试spark集群
./spark/bin/run-example org.apache.spark.examples.SparkPi spark://eb174:7077
9.2 Spark Master UI:http://eb174:8080/
