> Aggressively drop compression buffers in ORC OutStreams

> Project: Hive

> In Hive 0.11, when ORC's OutStream's were flushed they dropped all of the
> their buffers. In the patch for HIVE-4324, we inadvertently changed that
> behavior so that one of the buffers is held on to. For queries with a lot of
> writers and thus under significant memory pressure this can have a
> significant impact on the memory usage.
> Note that "hive.optimize.sort.dynamic.partition" avoids this problem by
> sorting on the dynamic partition key and thus only a single ORC writer is
> open at once. This will use memory more effectively and avoid creating ORC
> files with very small stripes, which will produce better downstream
> performance.
