Owen O'Malley commented on HIVE-4248:
-------------------------------------
This may result in ORC files with smaller stripes, but that seems far better
than letting the users get out of memory exceptions.
> Implement a memory manager for ORC

> With the large default stripe size (256MB) and dynamic partitions, it is
> quite easy for users to run out of memory when writing ORC files. We probably
> need a solution that keeps track of the total number of concurrent ORC
> writers and divides the available heap space between them.
