Devaraj Das commented on HBASE-7213:
------------------------------------
Apologies for not responding earlier.. But yes, the high level idea is to make
the recovery of META table fast and hence reduce the downtime of META should
the regionserver hosting the RS crash. By having a dedicated HLog for META, the
log splitting will be really simple (maybe just simple rename operations of
files; need to look at the code here)...
I am in the middle of plumbing through the code to make this work. Will
hopefully have something in a day or two.
> Have HLog files for .META. edits only

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