> I was running randomwalk trying to reproduce ACCUMULO-1625 and ran into what may be a
different issue.  Eventually concurrent random walk test failed because a file disappeared.
 After looking in the logs for a while, I determined the following happened.
>   # File I000005n.rf bulk imported into tableid q
>   # tableid q cloned into tableid u
>   # tableid q deleted
>   # scan of tableid u fails because I000005n.rf does not exist
> When a table is deleted it checks to see if any clones reference files in the table.
 If so, then it lets the Accumulo GC delete the deleted tables files.  If not, then the files
are deleted immediately.  Maybe something is going wrong with this check.
