Devaraj Das updated HBASE-7213:
-------------------------------
Attachment: 7213-in-progress.2.patch
A more complete version. Testing in progress. This patch adds APIs to do with
META in some classes (as opposed to a flag, as suggested by [~stack] earlier).
The logs for META region is written in a special file ending with ".META". The
SSH's process method treats META hlogs with higher priority and splits them
first, and as soon as the split is done, tries to assign them, and then goes on
to split other regions / assignments. I have not made changes to how the -ROOT-
region is handled, and the reason is that it is very very likely the case that
the -ROOT-'s region's edits are already persisted on disk (and in case folks
feel that -ROOT- should be handled as well, it probably can be done in a follow
up..).
> Have HLog files for .META. edits only
