Devaraj Das updated HBASE-7213:
-------------------------------
Attachment: 7213-2.4.patch
Okay, this patch addresses most of the comments. The thing that I have left
here not-handled is the (corner) case of the RS carrying the -root- region
dying before its edits are persisted (splitMetaLog doesn't take into account
-root- and the -root- edits are not written to a separate file either). The
reason is HBASE-3171 is removing the -root- table/region and so not much point
in trying to address -root- here ..
I have added an API getWAL(HRegionInfo) in RegionServerServices, and when the
argument is null, the default/common WAL is returned (imagine a WAL for meta,
and maybe some other regions, and a common WAL for everything else).
I have broken up the ServerShutdownHandler.process into two parts and moved
some code into MetaServerShutdownHandler.
> Have HLog files for .META. edits only

> written. This jira is to track an implementation of that.
