> The root table manages its own files (the accumulo GC does not delete file for the root
table).  It has fault tolerant code for replacing a set of files with a new file after a major
compaction.  This code has no test.  The code should be refactored so that it can be easily
tested.  I am uncertain if the existing code will work correctly with changes made in ACCUMULO-118.
> The code may be tested with CIAG (continuous ingest and agitation) , but its not guaranteed.
 The probability this will be tested with CIAG goes up the longer the test runs.  Since the
root tablet is only on one node, the probability of testing this w/ CIAG may go down as more
nodes are added and the likely hood of killing the root tablet decreases.  Therefore I think
it would be good to have a functional test for this.  Also, since there is uncertantity about
ACCUMULO-118 should probably add this for 1.6.0.
