["Raghu Angadi (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HADOOP-1826?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Raghu Angadi updated HADOOP-1826:
---------------------------------

    Attachment: HADOOP-1826-BlockCrcUpgrade.patch


BlockCrcUpgrade.patch : fixes BlockCrcUpgrade related classes.

Most changes are whitespace changes and most non-whitespace changes are because of 
class name changes.

Only functional change is that {{UpgradeObjectCollection.java}} now uses {{Class.getName()}} 
instead of {{Class.getCanonicalName()}} since thats what {{Class.forName()}} expects.

will attach a patch with white space chages ignored, for eay review.

> The following classes are "side" classes that aren't in files with the same name. This caused problems last night because ant compiled things in the wrong order and couldn't find one of the relevant classes. I think it would make the code easier to read and understand if you could always find a given class in the expected place.
