Subject [jira] [Commented] (ACCUMULO-1280) Add close method to iterators
Date Thu, 09 Jan 2014 21:05:51 GMT


Christopher Tubbs commented on ACCUMULO-1280:

Might be nice if, in the close method, we knew why it was closed... such as because the scan
completed (eg. an iterator on top of it finished) or because the scan was preempted, or if
a task was interrupted (canceled compaction, or scan session timeout). Some of these cases
might warrant additional methods instead of adding params to the close method, or the information
could be available in the iterator environment somehow.

> It would be useful if Accumulo iterators had a close method.  Accumulo would call this
when its finished using the iterator stack.
> How would this work w/ isolation?
> Is it ok to break the iterator API?
