Duo Zhang commented on HBASE-21788:
-----------------------------------
Yes we could add some debug logs for Open/CloseRegionProcedure, maybe also more
logs in the dispatcher?
> OpenRegionProcedure (after recovery?) is unreliable and needs to be improved

> Key: HBASE-21788
> URL: https://issues.apache.org/jira/browse/HBASE-21788
> Project: HBase
> Issue Type: Bug
> Affects Versions: 3.0.0
> Reporter: Sergey Shelukhin
> Priority: Critical
>
> Not much for this one yet.
> I repeatedly see the cases when the region is stuck in OPENING, and after
> master restart RIT is recovered, and stays WAITING; its OpenRegionProcedure
> (also recovered) is stuck in Runnable and never does anything for hours. I
> cannot find logs on the target server indicating that it ever tried to do
> anything after master restart.
> This procedure needs at the very least logging of what it's trying to do, and
> maybe a timeout so it unconditionally fails after a configurable period (1
> hour?).
> I may also investigate why it doesn't do anything and file a separate bug. I
> wonder if it's somehow related to the region status check, but this is just a
> hunch.
