> 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.
