-----------------------------------------------------------------

part2.v5 is an addendum that undoes some of v4 that was committed in june to make the patch
resemble branch-1's more and also undoes  the release note warning.

I should really just close this issue as it and file a new jira to commit this patch and then
branch-1 version.

> 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.
