Failed redirect for xxxxxxxxxxx

Failed while trying to construct the redirect url to the log server. Log Server url may not be configured Unknown container. Container either has not started or has already completed or doesn‘t belong to this node at all.

需要在mapred-site.xml 中添加

<name>mapreduce.jobhistory.address </name>
<value>hostName:10020</value>

<name>mapreduce.jobhistory.webapp.address</name>
<value>hostName:19888</value>

在 yarn-site.xml中添加

<property>
         <name>yarn.log.server.url</name>
         <value>http://hostName:19888/jobhistory/logs</value>
</property>

然后重新启动yarn,历史的不可查看。
