Work Description: pgaref opened a new pull request #1933:
URL: https://github.com/apache/hive/pull/1933
### What changes were proposed in this pull request?
Apply Sane Default for Tez Containers as Last Resort
### Why are the changes needed?
If Tez Container Size is an invalid value ( <= 0 ) then it falls back onto
the MapReduce configurations, but if the MapReduce configurations have invalid
values ( <= 0 ), they are excepted regardless and this will cause failures down
the road.
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?
Existing tests
