pan3793 opened a new pull request, #7865:
URL: https://github.com/apache/hbase/pull/7865

   HBase switched to `at.yawk.lz4:lz4-java` for security reasons, but it 
unintentionally introduced performance regression.
   
   https://github.com/yawkat/lz4-java/releases/tag/v1.10.4
   
   > These changes attempt to fix the native performance regression in 1.9+. 
They should have no functional or security impact.
   
   See the benchmark reports in Apache Celeborn and Apache Spark projects
