Aravindan Vijayan commented on AMBARI-20056:
--------------------------------------------
Refined the part of the code where AMS HBase tables policies are set such that
any compaction policy can be set for precision and aggregate tables.
Defaults
Precision Table (METRIC_RECORD)
hbase.hstore.defaultengine.compactionpolicy.class :
org.apache.hadoop.hbase.regionserver.compactions.FIFOCompactionPolicy
Aggregate Tables
hbase.hstore.engine.class :
org.apache.hadoop.hbase.regionserver.DateTieredStoreEngine
> FIFO compaction resulting in too many store files on large cluster

> Project: Ambari
> Issue Type: Bug
> Components: ambari-metrics
> Affects Versions: 2.5.0

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