Summary: Since the hashes should not be persisted in output_validator nor mock_env. Also updated NPHash64 to use 64-bit seed, and comments. Pull Request resolved: https://github.com/facebook/rocksdb/pull/7632 Test Plan: make check, and new build setting that enables modification to NPHash64, to check for behavior depending on specific values. Added that setting to one of the CircleCI configurations. Reviewed By: jay-zhuang Differential Revision: D24833780 Pulled By: pdillinger fbshipit-source-id: 02a57652ccf1ac105fbca79e77875bb7bf7c071f
