[jira] [Updated] (HBASE-12891) Parallel execution for Hbck checkRegionConsistency

     [ https://issues.apache.org/jira/browse/HBASE-12891?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Dave Latham updated HBASE-12891:
--------------------------------
    Attachment: HBASE-12891-v4-0.98.patch
                HBASE-12891-v4-branch-1.patch

Attaching corresponding v4 patches for branch-1 and 0.98.

[~syuanjiang] I'm not a committer, so someone else will have to jump in to drive it home.  Perhaps [~apurtell] would be willing to do the honors (again)?

> We have a lot of regions on our cluster ~500k and noticed that hbck took quite some time in checkAndFixConsistency().  [~davelatham] patched our cluster to do this check in parallel to speed things up.  I'll attach the patch.
