Description

We added support for predicate pushdown with Bloom filter predicate in 1.13. See KUDU-2483.
However instead of using the existing Bloom filter in Kudu which is used internally for index look ups, we decided to import the Cache, Hash and Space efficient Bloom filter from Impala which was written in C++.
We need to create a binary compatible Bloom filter in Java to be push down the Bloom filter predicate to Kudu servers from Java clients.
