> [HDFS-4015] counts and reports orphaned blocks
> {{numberOfBytesInFutureBlocks}} in safe mode. It was implemented in
> {{BlockManager}}. Per discussion in [HDFS-9129] which introduces the
> {{BlockManagerSafeMode}}, we can move code that maintaining orphaned blocks
> to this class.
> Leaving safe mode checks blocks with future GS in {{FSNamesystem}}. This code
> can also be moved to {{BlockManagerSafeMode}}.
