Subject [jira] [Created] (HDFS-3137) Bump LAST_UPGRADABLE_LAYOUT_VERSION
Date Fri, 23 Mar 2012 23:33:26 GMT

                 Key: HDFS-3137
                 URL: https://issues.apache.org/jira/browse/HDFS-3137
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: Eli Collins
            Assignee: Eli Collins

LAST_UPGRADABLE_LAYOUT_VERSION is currently -7, which corresponds to Hadoop 0.14. How about
we bump it to -16, which corresponds to Hadoop 0.18?

I don't think many people are using releases older than v0.18, and those who are probably
want to upgrade to the latest stable release (v1.0). They can always upgrade to v1.0 and then
eg 0.23 from there if they want.
