stack updated HBASE-7708:
-------------------------
Fix Version/s: 0.92.3
Marking for 0.92 (because of Matteo comment)
> deprecated call in region_mover.rb causing high cpu utilization
> ---------------------------------------------------------------
>
> Key: HBASE-7708
> URL: https://issues.apache.org/jira/browse/HBASE-7708
> Project: HBase
> Issue Type: Improvement
> Components: scripts
> Reporter: Eric Edgeworth
> Priority: Minor
> Fix For: 0.92.3
>
>
> We noticed high CPU utilization while using region_mover.rb to unload
> regions. Consulted with Stack, who suggested changing a line in
> region_mover.rb from (the deprecated):
> {code}
> table = getTable(admin.getConfiguration(), r.getTableDesc().getName())
> {code}
> to:
> {code}
> table = getTable(admin.getConfiguration(), r.getTableName())
> {code}
> In our tests this dropped CPU utilization from ~200% over the course of the
> unload to ~0.5% after startup, and allowed unload of ~200 regions to complete
> in ~7 minutes instead of the original ~18 minutes, so the change seems to fix
> the CPU utilization issue with no untoward side effects we could find.
