Description

Under this thread: http://search-hadoop.com/m/WSfKp1yJOFJ, John showed log from LoadIncrementalHFiles where the following is a snippet:

Looking at the above, it is not immediately clear which region was busy.

Region name should be included in the exception so that user can correlate with the region server where the problem occurs.
