stack updated HBASE-4015: ------------------------- Priority: Blocker (was: Critical) > Refactor the TimeoutMonitor to make it less racy > ------------------------------------------------ > > Key: HBASE-4015 > URL: https://issues.apache.org/jira/browse/HBASE-4015 > Project: HBase > Issue Type: Sub-task > Affects Versions: 0.90.3 > Reporter: Jean-Daniel Cryans > Priority: Blocker > Fix For: 0.92.0 > > > The current implementation of the TimeoutMonitor acts like a race condition > generator, mostly making things worse rather than better. It does it's own > thing for a while without caring for what's happening in the rest of the > master. > The first thing that needs to happen is that the regions should not be > processed in one big batch, because that sometimes can take minutes to > process (meanwhile a region that timed out opening might have opened, then > what happens is it will be reassigned by the TimeoutMonitor generating the > never ending PENDING_OPEN situation). > Those operations should also be done more atomically, although I'm not sure > how to do it in a scalable way in this case. -- This message is automatically generated by JIRA.
