> Impala's be/src/util/parquet-bloom-filter.* and Kudu's
> src/kudu/util/block_bloom_filter* are closely related. The tests in
> parquet-bloom-filter-test correspond closely with the tests in
> block_bloom_filter-test. Kudu made an improvement to the test to more
> accurate calculate the bloom filter false positive rate, and it would be
> useful to port that over to Impala.
> Kudu change:
> https://github.com/apache/kudu/commit/d1190c2b06a6eef91b21fd4a0b5fb76534b4e9f9
> It turns out that the parquet-bloom-filter-test is sensitive to the
> implementation of unordered_set, and it starts to fail with GCC/libstdc++ 10.
> The changes made for fixing the false positive rate fix the GCC 10 test
> failure as well.
