Subject Log errors about META
Date Mon, 10 Dec 2012 17:44:50 GMT
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.
