Resource Manager logs

1	2014-11-17 16:57:07,301 INFO org.apache.hadoop.yarn.server.resourcemanager.rmnode.RMNodeImpl: Node localhost:34650 reported UNHEALTHY with details: 1/1 local-dirs are bad: /var/lib/hadoop-yarn/cache/yarn/nm-local-dir; 1/1 log-dirs are bad: /var/log/hadoop-yarn/containers

 

 

遇到上面这样的问题，我的解决办法是：

 

 

在yarn-site.xml 里面配置

yarn.nodemanager.disk-health-checker.max-disk-utilization-per-disk-percentage
95.0

 

重启yarn即可解决！

 

yarn-daemon.sh stop nodemanager

yarn-daemon.sh start nodemanager
