Anoop Sam John commented on HBASE-19505:
----------------------------------------
bq.Nah. hbase.balancer.tablesOnMaster.systemTablesOnly is the exotic config.
You should have to go out of your way to set this. Small clusters will want
Master to be like any other RegionServer in cluster and carry its weight of
regions.
Clear now.. I some how got it the other way. Thought on system tables is
default. Now all ok.
> Disable ByteBufferPool by default at HM

> The main usage of the pool is while accepting bigger sized requests ie.
> Mutation requests. HM do not have any regions by default. So we can make
> this pool OFF in HM side. Still add a config to turn this ON.
