Subject [jira] [Created] (ACCUMULO-1628) NPE on deep copied dumped memoy iterator
Date Wed, 31 Jul 2013 17:01:52 GMT
Keith Turner created ACCUMULO-1628:
--------------------------------------

             Summary: NPE on deep copied dumped memoy iterator
                 Key: ACCUMULO-1628
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-1628
             Project: Accumulo
          Issue Type: Bug
    Affects Versions: 1.5.0, 1.4.0
            Reporter: Keith Turner
            Assignee: Keith Turner
             Fix For: 1.4.4, 1.5.1, 1.6.0


Accumulo may dump memory while a scan is running and transparently switch iterators from memory
to file.  If an iterator calls deepcopy after this happens, then seek will fail on the deep
copy.
