----------------------------------------
Summary: 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
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.
