Siddharth Seth commented on HIVE-12957:
---------------------------------------

Throwing a meaningful error would be ideal. However, a negative values comes directly from the YARN scheduler. In the past, getting certain parameters like headroom right on the YARN schedulers has required multiple iterations - and may still have corner cases which have not been explored. If a value like this comes in - we'd end up in a situation where jobs would fail randomly - until the issue is fixed by YARN.
Also, given that the number of splits is determined by available capacity - there's other cases where we ask for a single split - e.g. when the cluster is fully occupied and available capacity is 0. That scenario is almost as bad.
Requesting 1 split from FileInputFormat does not mean it returns only 1 split - it would still return 1 split per block.

The biggest problem with masking this is that we will not be able to report these issues so that they eventually get fixed.
