Keith Turner commented on ACCUMULO-3467:
----------------------------------------

[~elserj] thanks for the feedback.   I updated the patch.

The javadoc for the new compact method mentions that this is not allowed.  I 
added javadoc to the existing method stating its not allowed.  Do you think we 
need more than that?
