Hello,
In November I created HADOOP-15033: Use java.util.zip.CRC32C for Java 9
and above. It uses a new CRC32C class and relevant JVM intrinsics for
JDK 9+ if it is available, and keeps old behaviour for JDK 8.
rfe: https://issues.apache.org/jira/browse/HADOOP-15033
pull request: https://github.com/apache/hadoop/pull/291/
Performance study made for different ISAs and JDK versions demonstrates
significant improvement in case when platform class is used (see RFE).
Thanks to Steve Loughran who made valuable review comments, which were
addressed and applied to the pull request. The pull request is now also
rebased to latest trunk and again passes genericqa checks.
So this is a request to community for a second round of review.
