Subject [jira] [Commented] (HADOOP-8143) Change distcp to have -pb on by default
Date Thu, 08 Mar 2012 21:57:57 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8143?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13225570#comment-13225570
] 

Allen Wittenauer commented on HADOOP-8143:
------------------------------------------

Checksuming should get fixed vs. forcing the block size.  I suspect forcing block size will
break non-HDFS methods in surprising ways.

> We should have the preserve blocksize (-pb) on in distcp by default.        
> checksum which is on by default will always fail if blocksize is not the same.
