Jonathan Turner Eagles commented on TEZ-4130:
---------------------------------------------

[~abstractdog], now with TEZ-4271. Are we needing to increase the priority of 
this jira? Seems like unit test was needed, but perhaps some logic also.

> Config for hard limiting the number of splits

> During the investigation of a customer issue, I found that tez generated a 
> dag plan containing >4k tasks. It failed for hive because of bucket number 
> limitations (4k). It can be configured properly, e.g. bigger splits 
> (tez.grouping.min-size), but maybe it would be more convenient for users to 
> config a hard limit for the number of splits.
