Subject [jira] [Updated] (ACCUMULO-1628) NPE on deep copied dumped memory iterator
Date Tue, 09 Sep 2014 16:17:29 GMT

     [ https://issues.apache.org/jira/browse/ACCUMULO-1628?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Keith Turner updated ACCUMULO-1628:
-----------------------------------
    Attachment: ACCUMULO-1628-1.5.2-SNAPSHOT-3.patch

Another attempt   ACCUMULO-1628-1.5.2-SNAPSHOT-3.patch is relative to ACCUMULO-1628-1.5.2-SNAPSHOT-2.patch.
 I am going to merge this patch forward locally and try running the ITs in 1.6.

[~vines] if you have a chance to kick the tires on this patch, it would be appreciated.

> 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.
