Hbase rest server going down due to OOM error.Till now it was working fine.I am new to hbase. As per my understanding, hprof file is generated when server threw OOM error. And possible causes may be during compaction of hfiles or because of heavy writes.
Can anyone please help me to find out the reason.
At this point I would assume that compaction of hfiles shouldn't affect REST server.
Could you check/post the stdout and stderr file contents?
If you're sure about OOM, you might wanna increase heap size for REST server.
