Todd Lipcon commented on HDFS-1919: ----------------------------------- I patched too soon... this allows the upgrade and initial startup. But, then, on next start, the NN fails with: org.apache.hadoop.hdfs.server.common.InconsistentFSStateException: Directory /tmp/name1 is in an inconsistent state: file VERSION has no block pool Id. > 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 > Assignee: Todd Lipcon > Priority: Blocker > Fix For: 0.23.0 > > Attachments: hdfs-1919.txt > > > 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. -- This message is automatically generated by JIRA.
