      Description

      As mentioned in HDFS-5557, if a file has its last and penultimate block not completed and the file is being closed, the last block may be completed but the penultimate one might not. If this condition lasts long and the file is abandoned, LeaseManager will try to recover the lease and the block. But internalReleaseLease() will fail with invalid cast exception with this kind of file.
