Duo Zhang commented on HBASE-28582:
-----------------------------------
Ah, when implementing HBASE-28522, I found that there is a very big problem
that, in CloseExcessRegionReplicasProcedure, I forgot to call
super.serializeStateData...
This is a very critical problem as it may cause the loading of procedure store
to fail and bring down the whole cluster...
[~apurtell] I think we need to make a 2.5.9.1 release to include an addendum
for this fix...
> ModifyTableProcedure should not reset TRSP on region node when closing unused

> Found this when digging HBASE-28522.
> First, this is not safe as MTP does not like DTP where we hold the exclusive
> lock all the time.
> Second, even if we hold the exclusive lock all the time, as showed in
> HBASE-28522, we may still hang there forever because SCP will not interrupt
> the TRSP.
