Subject MR against snapshot causes High CPU usage on Datanodes
Date Wed, 13 May 2015 16:37:14 GMT
Hi,

I have recently started running MR on hbase snapshots but when the MR is
running there is pretty high CPU usage on datanodes and I start seeing IO
wait message in datanode logs and as soon I kill the MR on Snapshot
everything come back to normal.

What could be causing this ?

I am running cdh5.2.0 distribution.

Thanks,
Rahul
