> I often see some tez jobs stuck for a long time. I find partial tez reduce
> tasks seems to wait all inputs ready, and if inputs are not ready, the reduce
> tasks will wait forever.
> I think we can invoke the timeout version of *_waitForAllInputsReady,_* and
> this optimization was also mentioned in {*}HIVE-14042{*}. So, let's move
> forward with this optimization.
