Subject [jira] Created: (HADOOP-2797) Withdraw CRC upgrade from HDFS
Date Thu, 07 Feb 2008 21:49:08 GMT
Withdraw CRC upgrade from HDFS
------------------------------

                 Key: HADOOP-2797
                 URL: https://issues.apache.org/jira/browse/HADOOP-2797
             Project: Hadoop Core
          Issue Type: New Feature
          Components: dfs
    Affects Versions: 0.13.0
            Reporter: Robert Chansler
            Priority: Critical
             Fix For: 0.17.0


HDFS will no longer support upgrades from versions without CRCs for block data. Users upgrading
from version 0.13 or earlier must first upgrade to an intermediate (0.14, 0.15, 0.16) version
before upgrade to 0.17 or later.
