Subject [jira] [Updated] (HDFS-9694) Make existing DFSClient#getFileChecksum() work for striped blocks
Date Sat, 26 Mar 2016 08:01:25 GMT

     [ https://issues.apache.org/jira/browse/HDFS-9694?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Uma Maheswara Rao G updated HDFS-9694:
--------------------------------------
       Resolution: Fixed
     Hadoop Flags: Reviewed
    Fix Version/s: 3.0.0
     Release Note: Makes the getFileChecksum API works with striped layout EC files. Checksum
computation done by block level in the distributed fashion. The current API does not support
to compare the checksum generated with normal file and the checksum generated for the same
file but in striped layout.
           Status: Resolved  (was: Patch Available)

I have just committed this patch to trunk.

> This is a sub-task of HDFS-8430 and will get the existing API {{FileSystem#getFileChecksum(path)}}
work for striped files. It will also refactor existing codes and layout basic work for subsequent
tasks like support of the new API proposed there.
