Thanks for all the work on this. Looks good overall, just a few questions on compatibility:
It looks like this line in the merge checklist was not updated. Can you go into more details about the OM compatibility for lease recovery or other operations? > A new OM version number was introduced to prevent new client sending > atomic key overwrite request to old OM which does not support this feature. Additionally, new DataNode layout version "HBASE_SUPPORT" was added. Can you add some details about what changes on the disk layout after this feature is finalized? Is this related to the incremental chunk list or something more? Perhaps a more descriptive layout feature name would help here as well.
