> When Ozone client encounters an exception like ClosedContainerException, AlreadyClosedException,
RetryFailureException etc, it discards subsequent preallocated blocks from the same container.
While discarding the blocks, it should also validate if the block has any partial written
data before discarding it. This leads to incorrect size updation in OM.
