Log errors about META

[Brennon Church <br...@getjar.com>]

Hello,

I had some interesting trouble a couple days ago that I'm trying to track down.  Can anyone help me identify what would have caused the following log entries?  They showed up for about 1 hour, eventually going away without my having done anything.  The last time I see such entries in my logs was from July.

The one other post I saw with a similar error someone asked if the poster had manually edited META.  In case that question is asked here, I did not.

I'm running HBase 0.92.0.

Thanks.
