             Summary: Remove clientNode in FileUnderConstructionFeature
                 Key: HDFS-6583
                 URL: https://issues.apache.org/jira/browse/HDFS-6583
             Project: Hadoop HDFS
          Issue Type: Bug

{{FileUnderConstructionFeature}} contains two fields {{clientMachine}} and {{clientNode}}. {{clientNode}} keeps a reference of a {{DatanodeDescriptor}}. The reference be recomputed by consulting {{DatanodeManager}}.

This jira proposes to remove {{clientNode}} in the {{FileUnderConstructionFeature}} to simplify the code and to reduce overhead.
