Subject [jira] [Commented] (HDFS-1936) Updating the layout version from HDFS-1822 causes upgrade problems.
Date Wed, 01 Jun 2011 21:48:47 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1936?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13042464#comment-13042464
] 

Todd Lipcon commented on HDFS-1936:
-----------------------------------

+1 on the 0.22 patch.

We should probably add an 0.20.0 and 0.20.203 image tarball to these tests, too, given we
have the infrastructure, but we can do that separately for sure.

Some of the namenode logic that depends on layout version is broken because of this. Read
the comment for more description.
