Hadoop HA《hadoop-Yarn》

Hadoop HA《hadoop-Yarn》 1.Hadoop-Yarn

可参考我的文章《HadoopHA 搭建》

2.修改环境变量

cd /opt//hadoop-3.1.2/etc/hadoopvi hadoop-env.sh

export JAVA_HOME=/usr/lib/jvm/jdk1.8.0_111
export HDFS_NAMENODE_USER=root
export HDFS_DATANODE_USER=root
export HDFS_JOURNALNODE_USER=root
export HDFS_ZKFC_USER=root
export YARN_RESOURCEMANAGER_USER=root
export YARN_NODEMANAGER_USER=root

修改配置文件

vi mapred-site.xml

分发

scp yarn-site.xml mapred-site.xml [email protected]:`pwd`
scp yarn-site.xml mapred-site.xml [email protected]:`pwd`

启动测试

zkServer.sh start

start-dfs.sh

start-yarn.sh

启动命令（会产生两条警告信息）：
mr-jobhistory-daemon.sh start historyserver
可以使用命令启动：
mapred --daemon start historyserver
关闭命令：
 mr-jobhistory-daemon.sh stop historyserver
