Subject [jira] [Commented] (ACCUMULO-1628) NPE on deep copied dumped memory iterator
Date Tue, 11 Feb 2014 21:41:21 GMT

Josh Elser commented on ACCUMULO-1628:
--------------------------------------

What's the plan for this -- I'm planning to cut another RC tmrw for 1.5.1. Is this something
that's going to tried to be squeezed into 1.5.1? Is 1.5.2 acceptable?

> 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.
