> ResourceManager may fail due to name node in safe mode
> ------------------------------------------------------
>
> Key: YARN-2184
> URL: https://issues.apache.org/jira/browse/YARN-2184
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: resourcemanager
> Affects Versions: 2.4.0
> Reporter: Jeff Zhang
> Assignee: Jeff Zhang
>
> If the historyservice is enabled in resourcemanager, it will try to mkdir
> when service is inited. And at that time maybe the name node is still in
> safemode which may cause the historyservice failed and then cause the
> resouremanager fail. It would be very possible when the cluster is restarted
> when namenode will be in safemode in a long time.
> Here's the error logs:
> {code}
> Caused by:
> org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.hdfs.server.namenode.SafeModeException):
> Cannot create directory
> /Users/jzhang/Java/lib/hadoop-2.4.0/logs/yarn/system/history/ApplicationHistoryDataRoot.
> Name node is in safe mode.
> The reported blocks 85 has reached the threshold 0.9990 of total blocks 85.
> The number of live datanodes 1 has reached the minimum number 0. In safe mode
> extension. Safe mode will be turned off automatically in 19 seconds.
