> Number of tasks show in Tez UI with auto-reduce parallelism is misleading

>
> Ran a simple hive query (with tez) and "--hiveconf
> hive.tez.auto.reducer.parallelism=true" . This internally turns on tez's
> auto reduce parallelism.
> - Job started off with 1009 reduce tasks
> - Tez reduces the number of reducers to 253
> - Job completes successfully, but TEZ UI shows 1009 as the number of reducers
> (and 253 tasks as successful tasks). This can be a little misleading.
> I will attach the screenshots soon.
