Todd Lipcon updated HDFS-1073:
------------------------------
Resolution: Fixed
Release Note: The NameNode's storage layout for its name directories has
been reorganized to be more robust. Each edit now has a unique transaction ID,
and each file is associated with a transaction ID (for checkpoints) or a range
of transaction IDs (for edit logs).
Hadoop Flags: [Incompatible change, Reviewed] (was: [Incompatible change])
Status: Resolved (was: Patch Available)
