When running Sql queries on large datasets. Job fails with stack overflow warning and it shows it is requesting lots of executors.

Looks like there is no limit to number of executors or not even having an upperbound based on yarn available resources.

16/11/29 15:49:11 INFO yarn.YarnAllocator: Will request 44708 executor containers, each with 1 cores and 6758 MB memory including 614 MB overhead

If you notice in the error above, YARN is trying to request 24576 executor containers, whereas the available cores are 1719. The Driver is requesting for 52902 executor(s), which too high.

This exception should be fixed
