1.环境介绍
(1)操作系统RHEL6.2-64
(2)两个节点:spark1(192.168.232.147),spark2(192.168.232.152)
(3)两个节点上都装好了Hadoop 2.2集群
2.安装Zookeeper
(1)下载Zookeeper: http://apache.claz.org/zookeeper ... keeper-3.4.5.tar.gz
(2)解压到/root/install/目录下
(3)创建两个目录,一个是数据目录,一个日志目录
(4)配置:进到conf目录下,把zoo_sample.cfg修改成zoo.cfg(这一步是必须的,否则zookeeper不认识zoo_sample.cfg),并添加如下内容
(5)在/root/install/zookeeper-3.4.5/data目录下创建myid文件,并在里面写1
(6)把/root/install/zookeeper-3.4.5整个目录复制到其他节点
(7)登录到spark2节点,修改myid文件里的值,将其修改为2
(8)在spark1,spark2两个节点上分别启动zookeeper
(9)查看进程进否成在
3.配置Spark的HA
(1)进到spark的配置目录,在spark-env.sh修改如下
(2)把这个配置文件分发到各个节点上去
(3)启动spark集群
(4)进到spark2(192.168.232.152)节点,把start-master.sh 启动,当spark1(192.168.232.147)挂掉时,spark2顶替当master
(5)查看spark1和spark2上运行的哪些进程
4.测试HA是否生效
(1)先查看一下两个节点的运行情况,现在spark1运行了master,spark2是待命状态
(2)在spark1上把master服务停掉
(3)用浏览器访问master的8080端口,看是否还活着。以下可以看出,master已经挂掉
(4)再用浏览器访问查看spark2的状态,从下图看出,spark2已经被切换当master了
(1)操作系统RHEL6.2-64
(2)两个节点:spark1(192.168.232.147),spark2(192.168.232.152)
(3)两个节点上都装好了Hadoop 2.2集群
2.安装Zookeeper
(1)下载Zookeeper: http://apache.claz.org/zookeeper ... keeper-3.4.5.tar.gz
(2)解压到/root/install/目录下
(3)创建两个目录,一个是数据目录,一个日志目录
(4)配置:进到conf目录下,把zoo_sample.cfg修改成zoo.cfg(这一步是必须的,否则zookeeper不认识zoo_sample.cfg),并添加如下内容
dataDir=/root/install/zookeeper-3.4.5/data dataLogDir=/root/install/zookeeper-3.4.5/logs server.1=spark1:2888:3888 server.2=spark2:2888:3888
cd /root/install/zookeeper-3.4.5/data echo 1>myid
scp -r /root/install/zookeeper-3.4.5 root@spark2:/root/install/
cd /root/install/zookeeper-3.4.5/data echo 2>myid
cd /root/install/zookeeper-3.4.5 bin/zkServer.sh start
[root@spark2 zookeeper-3.4.5]# bin/zkServer.sh start JMX enabled by default Using config: /root/install/zookeeper-3.4.5/bin/../conf/zoo.cfg Starting zookeeper ... STARTED [root@spark2 zookeeper-3.4.5]# jps 2490 Jps 2479 QuorumPeerMain
(1)进到spark的配置目录,在spark-env.sh修改如下
export SPARK_DAEMON_JAVA_OPTS="-Dspark.deploy.recoveryMode=ZOOKEEPER -Dspark.deploy.zookeeper.url=spark1:2181,spark2:2181 -Dspark.deploy.zookeeper.dir=/spark" export JAVA_HOME=/root/install/jdk1.7.0_21 #export SPARK_MASTER_IP=spark1 #export SPARK_MASTER_PORT=7077 export SPARK_WORKER_CORES=1 export SPARK_WORKER_INSTANCES=1 export SPARK_WORKER_MEMORY=1g
scp spark-env.sh root@spark2:/root/install/spark-1.0/conf/
[root@spark1 spark-1.0]# sbin/start-all.sh starting org.apache.spark.deploy.master.Master, logging to /root/install/spark-1.0/sbin/../logs/spark-root-org.apache.spark.deploy.master.Master-1-spark1.out spark1: starting org.apache.spark.deploy.worker.Worker, logging to /root/install/spark-1.0/sbin/../logs/spark-root-org.apache.spark.deploy.worker.Worker-1-spark1.out spark2: starting org.apache.spark.deploy.worker.Worker, logging to /root/install/spark-1.0/sbin/../logs/spark-root-org.apache.spark.deploy.worker.Worker-1-spark2.out
[root@spark2 spark-1.0]# sbin/start-master.sh starting org.apache.spark.deploy.master.Master, logging to /root/install/spark-1.0/sbin/../logs/spark-root-org.apache.spark.deploy.master.Master-1-spark2.out
[root@spark1 spark-1.0]# jps 5797 Worker 5676 Master 6287 Jps 2602 QuorumPeerMain [root@spark2 spark-1.0]# jps 2479 QuorumPeerMain 5750 Jps 5534 Worker 5635 Master
(1)先查看一下两个节点的运行情况,现在spark1运行了master,spark2是待命状态
(2)在spark1上把master服务停掉
[root@spark1 spark-1.0]# sbin/stop-master.sh stopping org.apache.spark.deploy.master.Master [root@spark1 spark-1.0]# jps 5797 Worker 6373 Jps 2602 QuorumPeerMain
(4)再用浏览器访问查看spark2的状态,从下图看出,spark2已经被切换当master了
