Hi, Can you cross check if you have below property in Mapreduce2 -> config section on Ambari UI?

mapreduce.jobhistory.done-dir = /mr-history/done

If not and try adding this property under "Advanced mapred-site" section, the default value of this parameter is "/mr-history/done"

Frankly i don't know how it got removed from your cluster 🙂 but this property comes default when you install History server. Also please accept the answer if that helped you to resolve this issue.

hi,

In my case, the permission on the following folder caused the issue.

/hadoop/mapreduce/jhs/mr-jhs-state

The following log message at /var/log/hadoop-mapreduce/mapred/mapred-mapred-historyserver-iml6.log helped me solve it. For some reason the files were owned by Yarn, when I given permission to the group I could see the files were rewritten by mapred.

IO error: /hadoop/mapreduce/jhs/mr-jhs-state/LOCK: Permission denied
