----------------------------------------
Looks interesting. Rebased the patch due to conflict with HADOOP-15033. Let's
see how precommit says
> Hadoop CRC implementation using Intel ISA-L library
> ---------------------------------------------------
>
> Key: HDFS-12046
> URL: https://issues.apache.org/jira/browse/HDFS-12046
> Project: Hadoop HDFS
> Issue Type: Improvement
> Reporter: luhuichun
> Assignee: Sammi Chen
> Priority: Major
> Attachments: HDFS-12046-001.patch, HDFS-12046-002.patch, ISA-L CRC
> Performance Report using intel ISA-L.pdf
>
>
> Intel ISA-L open source library provides set of highly optimized functions
> for RAID, erasure code, CRC, cryptographic hash, encryption, and compression.
> Ref. https://github.com/01org/isa-l. HDFS-EC has already integrated ISA-L and
> added the necessary building options support for Hadoop. For Hadoop CRC, we
> recently explored more, developing a Hadoop CRC using Intel ISA-L, performing
> a test on Broadwell and Skylake servers, comparing the performance against
> Hadoop native CRC. On Broadwell/Skylake, ISA-L CRC has about 8%~ performance
> gain over Hadoop native CRC. We suggest adding a new Hadoop native CRC using
> the ISA-L library, the extra advantage is it’s already optimized when we
> upgrade to new servers and Hadoop developers don’t have to maintain their own
> bunch of ASM codes.
