Jira Cleanup

[Sönke Liebau <so...@opencore.com.INVALID>]

Hi all,

I've spent some time with jira and identified a few tickets that might be
worth looking at again / closing if there is no appetite for them.

KAFKA-1906 <https://issues.apache.org/jira/browse/KAFKA-1906> & KAFKA-3925
<https://issues.apache.org/jira/browse/KAFKA-3925> - Both these ticket
refer to the default for log.dirs and recommend moving this away from /tmp/
- I've not found many other references to this topic, is there any interest
in discussing this? Otherwise I think we can safely close both tickets.

KAFKA-2333 <https://issues.apache.org/jira/browse/KAFKA-2333> - Add rename
topic support
KAFKA-976 <https://issues.apache.org/jira/browse/KAFKA-976> - Order-Preserving
Mirror Maker Testcase
KAFKA-2493 <https://issues.apache.org/jira/browse/KAFKA-2493> - Add ability
to fetch only keys in consumer

<https://issues.apache.org/jira/browse/KAFKA-2493>
As usual, I've left comments on the tickets and will close them if there
are no objections in the next few days.

Best,
Sönke
