> The DataNode reserves space for a full block when creating an RBW block
> (introduced in HDFS-6898).
> The reserved space is released incrementally as data is written to disk and
> fully when the block is finalized. However if the client process terminates
> unexpectedly mid-write then the reserved space is not released until the DN
> is restarted.
