-------------------------------
Your scenario may be possible [~devaraj] I need to look at it more and try and
put in measures to prevent it.
It is not the case here though.
Here are current edits in hbase:meta:

The info:regioninfo is missing.
This region has not been split. which as best as I can tell, is time we'd
remove the info:regioninfo entry.
I went back over the moved off hfiles and recovered edits files and only see
mention of the Put of the original info:regioninfo edit. There is no 'Delete'.
It looks like the edit was 'dropped'. Let me see if I can find the time at
which the edit was dropped.

> Project: HBase
> Issue Type: Bug
> Reporter: stack
> Fix For: 1.0.1
>
>
> Testing 1.0.0 trying long-running tests.
> A row in hbase:meta was missing its HRI entry. It caused the job to fail.
> Around the time of the first task failure, there are balances of the
> hbase:meta region and it was on a server that crashed. I tried to look at
> what happened around time of our writing hbase:meta and I ran into another
> issue; 20 logs of 256MBs filled with WrongRegionException written over a
> minute or two. The actual update of hbase:meta was not in the logs, it'd been
> rotated off.
