| 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. |
