hadoop集群启动和关闭脚本

开启集群：

#!/bin/bash

#start zookeeper
ssh hadoop001 "$ZOOKEEPER_HOME/bin/zkServer.sh start"
ssh hadoop002 "$ZOOKEEPER_HOME/bin/zkServer.sh start"
ssh hadoop003 "$ZOOKEEPER_HOME/bin/zkServer.sh start"

sleep 8

#start hdfs+yarn+jobhistory
ssh hadoop001 "$HADOOP_HOME/sbin/start-dfs.sh"
ssh hadoop001 "$HADOOP_HOME/sbin/start-yarn.sh"

sleep 5s

ssh hadoop002 "$HADOOP_HOME/sbin/yarn-daemon.sh start resourcemanager"

ssh hadoop001 "$HADOOP_HOME/sbin/mr-jobhistory-daemon.sh start historyserver"

sleep 3
sh /home/hadoop/hadoopclustershell/jps.sh

关闭集群：

#!/bin/bash

#stop jobhistory+yarn+hdfs

ssh hadoop001 "$HADOOP_HOME/sbin/mr-jobhistory-daemon.sh stop historyserver"

ssh hadoop001 "$HADOOP_HOME/sbin/stop-yarn.sh"
ssh hadoop002 "$HADOOP_HOME/sbin/yarn-daemon.sh stop resourcemanager"

ssh hadoop001 "$HADOOP_HOME/sbin/stop-dfs.sh"

sleep 5

#stop zookeeper
ssh hadoop001 "$ZOOKEEPER_HOME/bin/zkServer.sh stop"
ssh hadoop002 "$ZOOKEEPER_HOME/bin/zkServer.sh stop"
ssh hadoop003 "$ZOOKEEPER_HOME/bin/zkServer.sh stop"

sh /home/hadoop/hadoopclustershell/jps.sh
