Subject [jira] [Created] (ACCUMULO-1629) Files in cloned table disappear when source deleted

Keith Turner created ACCUMULO-1629:
--------------------------------------

             Summary: Files in cloned table disappear when source deleted
                 Key: ACCUMULO-1629
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-1629
             Project: Accumulo
          Issue Type: Bug
            Reporter: Keith Turner
             Fix For: 1.6.0


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.
