ShuMing Li commented on AMBARI-20056:
-------------------------------------

My distributed Hbase version is 1.2.6, use default compaction policy, we get the exception below:

>  java.io.IOException: java.io.IOException: Unable to load configured store engine 'org.apache.hadoop.hbase.regionserver.DateTieredStoreEngine'

So which compaction policy should we use？

> Set Data Tiered compaction for all tables except METRIC_RECORD
> This will allow number of store files to go down over time.  On a 500 node cluster AMS can become in-operational after creating 18K store files and no compaction.
