Subject [jira] [Created] (HDFS-1919) Upgrade to federated namespace fails
Date Wed, 11 May 2011 22:01:48 GMT
Upgrade to federated namespace fails

                 Key: HDFS-1919
                 URL: https://issues.apache.org/jira/browse/HDFS-1919
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: name-node
    Affects Versions: 0.23.0
            Reporter: Todd Lipcon
            Priority: Blocker
             Fix For: 0.23.0

I formatted a namenode running off 0.22 branch, and trying to start it on trunk yields:
org.apache.hadoop.hdfs.server.common.InconsistentFSStateException: Directory /tmp/name1 is
in an inconsistent state: file VERSION has clusterID mising.

It looks like 0.22 has LAYOUT_VERSION -33, but trunk has LAST_PRE_FEDERATION_LAYOUT_VERSION
= -30, which is incorrect.
