> [java] Improve space complexity about prune hash partitions for in-list
> predicate
> Pruning hash partitions for in-list predicate at java-client, the logic
> codes has a high space complexity, and it may cause java-client out

> This patch fixes the problem and provide a recursive algorithm, that
> uses a method like 'deep first search' to pick all combinations and
> try to release PartialRow objects ASAP.
