Todd Lipcon commented on HDFS-2106:
-----------------------------------
This stuff is very interesting!
Do you have some fleshed out designs on how to handle some of the operations
which are currently "transactional" between blocks and inodes? eg how is it
handled when a pipeline is broken, and the block recovery has the side effect
of changing an INodeFileUnderConstruction into an INodeFile? I don't see leases
anywhere in the API diagram either.
