Jonathan Hsieh updated HBASE-16117:
-----------------------------------
Resolution: Fixed
Fix Version/s: (was: 1.2.5)
(was: 1.1.7)
(was: 1.3.1)
Release Note:
(This change will be irrelevant after HBASE-16774 lands).
There is a subtle change with error handling when a connection is not able to
connect to ZK. Attempts to create a connection when ZK is not up will now fail
immediately instead of silently creating and then failing on a subsequent
HBaseAdmin call.

Status: Resolved (was: Patch Available)
As noted earlier, I'm abandoning the attempt to port to 1.x currently.

> Spark seems to instantiate multiple instances of output formats within a
> single process. When mapred.TableOutputFormat (not
> mapreduce.TableOutputFormat) is used, this may cause connection leaks that
> slowly exhaust the cluster's zk connections.
> This patch fixes that.
