Yarn Service : Error while starting -- CDH5

[#1]

Hi ALL ,

I installed cdh5 manager and tried to bringup services HDFS , Yarn and cloud era manager .
While starting YArn service , it exited with below Error : [NB : <machine> --> host name]

Default file system [hdfs://<machine>:8020]

Service org.apache.hadoop.mapreduce.v2.hs.HistoryFileManager failed in state INITED; cause: org.apache.hadoop.yarn.exceptions.YarnRuntimeException: Error creating done directory: [hdfs://<machine>:8020/user/history/done]
org.apache.hadoop.yarn.exceptions.YarnRuntimeException: Error creating done directory: [hdfs://<machine>:8020/user/history/done]

Any one has any idea about this Error ?

Thanks

isn't this unsafe?

Quite unsafe.

[hdfs@node1 ~]$ hdfs dfs -mkdir -p /user/history
[hdfs@node1 ~]$ hdfs dfs -chmod -R 1777 /user/history
[hdfs@node1 ~]$ hdfs dfs -chown mapred:hadoop /user/history
