stack updated HBASE-1495:
-------------------------
Attachment: 1495.patch
Attachment fixes two issues: 1. splitting, we were updating .META. using one
side of split for both splitA and splitB, and 2., on processing of split
removals, we were getting NPE.
Still to do are the following phenomeon:
1. On remove of a info:splitA or info:splitB from a parent regions' row, on the
next meta scan, splitA and splitB are missing even though only one side has
been removed. Because we think both removed, we'll remove the parent injuring
the daughter split still being served.
2. I'm seeing store files that have keys in excess of the start and end row of
hosting region.
Still working on 1 and 2.
