-------------------------------------------

Hey,

Could someone with a deeper knowledge of HDFS internals comment on what work would need to
be done after this refactoring to complete https://issues.apache.org/jira/browse/HADOOP-3799?
Any insight here would be much appreciated!

Later,
Jeff

> Currently FSNamesystem contains a big amount of code that manages blocks and replicas.
The code scatters in FSNamesystem and it is hard to read and maintain. It would be nice to
move the code to a separate class called, for example, BlockManager.
