Subject [jira] [Created] (HDFS-6034) DN registration should use DataNodeLayoutVersion instead of NameNodeLayoutVersion
Date Fri, 28 Feb 2014 03:15:20 GMT
Haohui Mai created HDFS-6034:
--------------------------------

             Summary: DN registration should use DataNodeLayoutVersion instead of NameNodeLayoutVersion
                 Key: HDFS-6034
                 URL: https://issues.apache.org/jira/browse/HDFS-6034
             Project: Hadoop HDFS
          Issue Type: Sub-task
    Affects Versions: HDFS-5535 (Rolling upgrades)
            Reporter: Haohui Mai


Currently the registrationID is in the form of {{BlockPoolID-NNLayoutVersion}}. When the NN
bumps the layout version during rolling upgrade, the DNs will fail to register with the new
NN and exit, regardless whether the new software version is used.
