Subject WARN CleanerChore - Error while cleaning the logs
Date Tue, 29 Jan 2013 07:27:07 GMT
Hi,

Recently after upgrading to 0.94.3, my unit test which is using HBase mini cluster keeps throwing
this warning. 
Why does it want to delete a table folder?
Can someone elaborate on this exception?

My test it self is setting up two tables, in which only one is used. The one in the errors
is the unused one.
