Subject [jira] [Commented] (HDFS-6560) Byte array native checksumming on DN side
Date Fri, 04 Jul 2014 02:23:35 GMT

    [ https://issues.apache.org/jira/browse/HDFS-6560?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14052104#comment-14052104
] 

Tsz Wo Nicholas Sze commented on HDFS-6560:
-------------------------------------------

Sure. I just want to point out that we should not blindly use native for all cases.  In the
current implementation, native will be used if it is available.  However, native is not always
the best according to the benchmarks.
