Found another issue, with use of SynchronousQueue. The executor throws rejected exception if we submit a task, when the number of running tasks has reached the maximum thread limit.

Should I close this jira as invalid and file another jira or just alter this jira and submit the fix?

> UnorderedPartitionedKVWriter add task to the executor, but does not wait for them to finish before starting the final merge. This can cause finalMerge to fail or write incorrect data.
