[jira] [Created] (HBASE-6223) Document hbck improvements: HBASE-6173, HBASE-5360

             Summary: Document  hbck improvements: HBASE-6173, HBASE-5360
                 Key: HBASE-6223
                 URL: https://issues.apache.org/jira/browse/HBASE-6223
             Project: HBase
          Issue Type: Task
          Components: documentation, hbck
            Reporter: Jimmy Xiang


We had a couple hbck improvements recently: HBASE-6173 and HBASE-5360.
We should document them. Especially, for HBASE-5360, it's something
one normally doesn't do.

[jira] [Commented] (HBASE-6223) Document hbck improvements: HBASE-6173, HBASE-5360

Posted by "Jonathan Hsieh (JIRA)" <ji...@apache.org>.
    [ https://issues.apache.org/jira/browse/HBASE-6223?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13409222#comment-13409222 ] 

Jonathan Hsieh commented on HBASE-6223:
---------------------------------------

Motivation for HBASE-5360: We encountered a situation where a parent was marked off-line in meta, where data still existed in HDFS, and where we actually wanted to restore the data that was in the FS.  I believe the old behavior was to skip these regions with the assumption that daughter regions were good.  In this particular case, the daughter regions were not -- I believe one of the two were missing, and we wanted an option to "revive" the parent region.  This would likely cause an overlap with the surviving daughter region -- but we already had mechanisms to handle that (-fixHdfsOverlaps).  The -fixSplitParents option is should not normally be used (it is not part of -fixAll).

Motivation for HBASE-6173: We ran into a situation withe cluster that had a large number of regions (~20k, for 50 nodes or so).  The file system operations for loading this data, even though it happened in parallel took a very long time.  This addition allowed us just to reduced the time for a report by only focusing on a particular table.

stack commented on HBASE-6223:
------------------------------

+1 on commit.  On commit add in a 'the' between 'in' and 'right'.  Should that be 'or not deployed' (add 'or') and 'so you can' -- add a 'so'?  Maybe break up the big sentence.  Its hard to pass.  Good on you Jimmy.

+Once a region is split, the offline parent will be cleaned up automatically. Sometimes, daughter regions
+are split again before their parents are cleaned up. HBase can clean up parents in right order. However,
+if there is a lingering offline split parent, i.e. it's in META, in HDFS, not deployed, HBase can't
+clean it up, you can use the <code>-fixSplitParents</code> option to reset the parent in META to be
+online and not split so that hbck can merge it with other regions with options to fix
+overlapping regions. This option should not normally be used, and it is not in <code>-fixAll</code>.
