[jira] [Updated] (HADOOP-8143) Change distcp to have -pb on by default

     [ https://issues.apache.org/jira/browse/HADOOP-8143?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Mithun Radhakrishnan updated HADOOP-8143:
-----------------------------------------
    Attachment: HADOOP-8143.1.patch

Tentative fix. This preserves block-size by default (but only if -p isn't specified at all). This assumes that if the user said {{-pug}}, then block-size was deliberately left out.

> 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.
