一,配置history server
1.配置history server,在etc/hadoop/mapred-site.xml中配置以下内容.
<span style="font-size:18px;"><span style="font-size:18px;"> <property><name>mapreduce.jobhistory.address</name><value>localhost:10020</value> </property> <property><name>mapreduce.jobhistory.webapp.address</name><value>localhost:19888</value> </property></span></span>
2.把配置分发到所有服务器
3.启动服务,以localhost这台服务器上执行以下语句:
mr-jobhistory-daemon.sh start historyserver
二 ,配置timeline server
1.配置history server,在etc/hadoop/yarn-site.xml中配置以下内容.
<span style="font-size:18px;"><!–start timeline settings –> <property><description></description><name>yarn.timeline-service.hostname</name><value>localhost</value> </property> <property> <description>Address for the Timeline server to start the RPC server.</description> <name>yarn.timeline-service.address</name> <value>${yarn.timeline-service.hostname}:10200</value></property><property> <description>The http address of the Timeline service web application.</description> <name>yarn.timeline-service.webapp.address</name> <value>${yarn.timeline-service.hostname}:8188</value></property><property> <description>The https address of the Timeline service web application.</description> <name>yarn.timeline-service.webapp.https.address</name> <value>${yarn.timeline-service.hostname}:8190</value></property><property> <description>Handler thread count to serve the client RPC requests.</description> <name>yarn.timeline-service.handler-thread-count</name> <value>10</value></property><property> <description>Enables cross-origin support (CORS) for web services where cross-origin web response headers are needed.

2.把配置分发到所有服务器
3.启动服务,以localhost这台服务器上执行以下语句:
yarn-daemon.sh start historyserver
，觉得自己做的到和不做的到，其实只在一念之间
