> Key: HBASE-28774
> URL: https://issues.apache.org/jira/browse/HBASE-28774
> Project: HBase
> Issue Type: Improvement
> Components: meta
> Reporter: Ranganath Govardhanagiri
> Assignee: Ranganath Govardhanagiri
> Priority: Major
>
> 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.
