[jira] [Commented] (HBASE-7287) HBase inconsistencies when merge failing on "Files have same sequenceid"

["Jean-Marc Spaggiari (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-7287?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13510965#comment-13510965 ] 

Jean-Marc Spaggiari commented on HBASE-7287:
--------------------------------------------

Finally, it's not possible to move the newRegionDir creation after the sequenceID check since some sequenceID for some Familly files might be correct and will need to create the new column family dirs (makeColumnFamilyDirs). So instead of moving the directory creation, here is a patch to remove the created directory if the merge is failing, to avoid system inconsistencies.

> When regions merge is failing because the files have the same sequenceID, the expected region is still created even if it's not used, which leaves the system with inconsistencies. The new region creation should be moved after the sequenceID test to avoid this issue, until we find a way to merge regions with the same sequenceID.
