Hello Kudu Jenkins,

to look at the new patch set (#8).
Change subject: [java client] KUDU-1643 Prune hash partitions based on IN-list
predicates
......................................................................
[java client] KUDU-1643 Prune hash partitions based on IN-list predicates
PartitionPruner is updated to search all combinations of in-list column
values and prune hash partitions where possible.
This also fixes a small issue in the C++ version of the algorithm:
previously the implementation would always consider the final hash
component to be constrained. The bug (as far as I can tell) doesn't lead
to erroneous results, but does cause more partition ranges to be
created, which results in more memory overhead and compute overhead to
compute the pruning.
