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

             Summary: The return type of FSNamesystem.getBlockCollection should 
be changed to INodeFile
                 Key: HDFS-9527
                 URL: https://issues.apache.org/jira/browse/HDFS-9527
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: namenode
            Reporter: Tsz Wo Nicholas Sze
            Assignee: Tsz Wo Nicholas Sze
            Priority: Minor


FSNamesystem.getBlockCollection always returns INodeFile.  It avoids 
unnecessary conversion from BlockCollection to INode/INodeFile after the change.
