Duo Zhang resolved HBASE-21165.
-------------------------------
Assignee: (was: Michael Stack)
Resolution: Won't Fix
We use RegionProcedureStore now, close the WALProcedureStore related issues as
Won't Fix.
> During ProcedureStore load, there is no listing of progress...

> Key: HBASE-21165
> URL: https://issues.apache.org/jira/browse/HBASE-21165
> Project: HBase
> Issue Type: Bug
> Components: amv2, Operability
> Reporter: Michael Stack
> Priority: Major
> Attachments: HBASE-21165.branch-2.1.001.patch
>
>
> I have a Master that crashed on a large cluster with hundreds of outstanding
> Procedure WALs and (probably --TBD) a few million Procedures to load. It is
> taking a long time (two hours)...
> There were STUCK procedures that were preventing clean-up of the old WALs.
> I can tell we are making progress by enabling TRACE on the Procedure Store.
> Better would be an emission as we made progress through the files with an
> output after every so many procedures loaded.
> Then, post-load, there is a long time spent sorting-out the Procedure
> image... We are in finish for ages doing stuff like:
> {code}

> In this case, it took 1.25 hours before we starting showing progress in the
> log. Let me add progress output (Separately am looking at how to do speedup).
