-------------------------------
This seems breaks TestShell.
Let me confirm.

> Key: HBASE-28212
> URL: https://issues.apache.org/jira/browse/HBASE-28212
> Project: HBase
> Issue Type: Improvement
> Components: master, proc-v2
> Reporter: Duo Zhang
> Assignee: Duo Zhang
> Priority: Major
> Fix For: 2.6.0, 2.4.18, 3.0.0-beta-1, 2.5.7
>
>
> In HBASE-28210, we need to synchronized on RootProcedureState when updating
> procedure store, which will decrease the performance a lot when there are
> lots of sub procedures for a procedure, such as SCP, so it will impact MTTR.
> But actually, SCP does not support rollback, so I do not think we need to
> maintain this information. If so, I think we do not need the synchronization
> added in HBASE-28210, at least for SCP then. This could get the performance
> back.
