Subject [jira] [Commented] (HBASE-4991) Provide capability to delete named region
Date Thu, 26 Jan 2012 23:25:45 GMT

    [ https://issues.apache.org/jira/browse/HBASE-4991?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13194267#comment-13194267
] 

Jonathan Hsieh commented on HBASE-4991:
---------------------------------------

Oops -- wasn't looking at the comment tab.

There is similar code in OnlineMerge and uber hbck.

The code in uber hbck creates a new empty region, closes old regions,  moves data into the
new empty region, and then activates the new now populated region.

Beware -- I found just closing a region seems to have left data around in the HMaster's memory
which cause disabling to have problems in the 0.90.x version.  I'm in the process of porting
to trunk/0.92 currently and am finding out if there are similar or different problems.  I
think I saw something else in closeRegion recently that I need to try out -- don't remember
which version that is however.
