Xuan Gong resolved YARN-2184. ----------------------------- Resolution: Duplicate > 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.
