Subject [jira] [Commented] (HDFS-6560) Byte array native checksumming on DN side
Date Tue, 24 Jun 2014 20:14:25 GMT

    [ https://issues.apache.org/jira/browse/HDFS-6560?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14042609#comment-14042609
] 

James Thomas commented on HDFS-6560:
------------------------------------

I am using JDK 1.7. And yes, I mean the verifyChunkedSums code path in DataChecksum that calls
out repeatedly to either PureJavaCrc32 or PureJavaCrc32C.

Do you think the improvements you made to the Java code could also be made to the native implementation?
