The CompatibilityTest of bloom_filter-test.cc is used to test cross compatibility of

Bloom filters between parquet-mr and parquet-cpp. It reads the Bloom filter binary

generated by the Bloom filter class in the parquet-mr project and tests whether the

values inserted before could be filtered or not.

The Bloom filter binary is generated by three steps from Parquet-mr:

Step 1: Construct a Bloom filter with 1024 bytes of bitset.

Step 2: Insert hashes of "hello", "parquet", "bloom", "filter" strings to Bloom filter

by calling hash and insert APIs.

Step 3: Call writeTo API to write to File.
