Ranganath Govardhanagiri updated HBASE-28774:
---------------------------------------------
Description: During some of the incidents, it is observed that when
hbase:meta is colocated with high load (or hotspotting) region, that makes meta
unavailable and causes availability issues. This item is to provide a way to
load balance such regions such that meta is not impacted. (was: In different
instances, we have seen that RITs were failing for SYSTEM.CATALOG and
HBase.META tables when they are hosted on the same host and causing an outage.
Even though system tables are being hosted on different hosts based on sys rs
group, we are seeing this problem when patching or deployments or Master
failovers and the regions of SYSTEM.CATALOG and HBase.META tables hosted on the
same host.
An idea is to make sure regions of SYSTEM.CATALOG and HBase.META hosted on
separate hosts would help us to reduce the load on the hosts which is causing
the outages and RITs failures.)
> Protect hbase:meta from any hotspotting regions by balancing them to
> different region servers
