Aaron T. Myers commented on HDFS-4746:
--------------------------------------

Should we go ahead and close out this JIRA, since I don't think anyone intends to maintain 2.2 and 2.0 anymore?

> In some cases the last block replica of a file can be reported after the file was closed. In this case file inode is of type INodeFile. BlockManager.addStoredBlock() though expects it to be INodeFileUnderConstruction, and therefore class cast to MutableBlockCollection fails.
