> This jira tracks the effort of refactoring inner classes
> {{BlockManager$BlockToMarkCorrupt}} and {{BlockManager$ReplicationWork}} in
> {{hdfs.server.blockmanagement}} package. As the line number of
> {{BlockManager}} is getting larger than 2000, we can move those two inner
> classes out of the it.
> Meanwhile, the logic in method {{computeReplicationWorkForBlocks}} can be
> simplified if we extract code sections to _schedule replication_ and to
> _validate replication work_ to private helper methods respectively.
