Subject [jira] [Commented] (HBASE-4379) [hbck] Does not complain about tables with no end region [Z,]
Date Mon, 25 Jun 2012 18:09:43 GMT

    [ https://issues.apache.org/jira/browse/HBASE-4379?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13400739#comment-13400739
] 

Anoop Sam John commented on HBASE-4379:
---------------------------------------

The case I was mentioning is one table having 3 regions is disabled now. Then suppose 2 regions
(1st and last) are deployed in some RS. Now when the HBCK is run, we expect it will fix this
making these 2 regions offline.
But when running the checkRegionChain, it might report as a hole and if the fixHdfsHoles option
is ON, it might create a new region. [This is unwanted I think]

In testRegionShouldNotBeDeployed() if we make the region [ddd,) also deployed on some RS,
we can see it report a region hole error and trying to fix the same.
