    • Release Note:
      Implemented Lease Recovery to sync the last bock of a file. Added ClientDatanodeProtocol for client trigging block recovery. Changed DatanodeProtocol to support block synchronization. Changed InterDatanodeProtocol to support block update.

      Description

      In order to support file append, a GenerationStamp is associated with each block. Lease recovery will be performed when there is a possibility that the replicas of a block in a lease may have different GenerationStamp values.

      For more details, see the documentation in HADOOP-1700.
