Todd Lipcon commented on HDFS-3528:
-----------------------------------
hey [~james.thomas] -- now that HDFS-6865 is committed, are we missing any
pieces here? Or are we all-native-all-the-time throughout the write pipeline
now?
> Use native CRC32 in DFS write path
> ----------------------------------
>
> Key: HDFS-3528
> URL: https://issues.apache.org/jira/browse/HDFS-3528
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: datanode, hdfs-client, performance
> Affects Versions: 2.0.0-alpha
> Reporter: Todd Lipcon
> Assignee: James Thomas
>
> HDFS-2080 improved the CPU efficiency of the read path by using native
> SSE-enabled code for CRC verification. Benchmarks of the write path show that
> it's often CPU bound by checksums as well, so we should make the same
> improvement there.
