stack commented on HBASE-21788:
-------------------------------
24hrs, 47.379sec is interesting. Did you check the UI lock and procedures page?
It can help figuring procedure state and who has locks on what. Would have been
good to see if pid=32701 was still around or what state it was in.
> OpenRegionProcedure (after recovery?) is unreliable and needs to be improved

> 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.
