[jira] [Created] (HDFS-3137) Bump LAST_UPGRADABLE_LAYOUT_VERSION

Bump LAST_UPGRADABLE_LAYOUT_VERSION
-----------------------------------

                 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.
