> Running hive export on a table with a large number of partitions winds up making the
metastore and client run out of memory. The number of places we wind up having a copy of the
entire partitions object wind up being as follows:
> Metastore
>    * (temporarily) Metastore MPartition objects
>    * List<Partition> that gets persisted before sending to thrift
>    * thrift copy of all of those partitions
> Client side
>    * thrift copy of partitions
>    * deepcopy of above to create List<Partition> objects
>    * JSONObject that contains all of those above partition objects
>    * List<ReadEntity> which each encapsulates the aforesaid partition objects.
> This memory usage needs to be drastically reduced.
