[jira] Commented: (HBASE-483) Merge tool won't merge two overlapping regions

["stack (JIRA)" <ji...@apache.org>]

stack commented on HBASE-483:
-----------------------------

To make this work, need to fix mergeStoreFiles to instead of appending to the new store file the passed src store files, instead it interweaves as scanners do currently.  Will also have to amend the check in HRegion which prevents merging of non-adjacent regions so it allows merging overlapping regions.

> hbase-480 adds a merge tool. Seems to work for two adjacent regions in tests but not for the case where we've made two overlapping regions: i.e. both have a start key of 'A' but one regions endkey is less than the end key of the others (See up on Lars cluster hbase-471).  I ran the merge and it made a new region with the right start and end keys but there was nothing in it.
> We need this tool to do fix up when hbase goes awry.
