      Description

      HDFS-617 was brought into branch-0.20-security/branch-1 to support non-recursive create, along with HADOOP-6840 and HADOOP-6886. However, the changes in HDFS was done in an incompatible way, making the client unusable against older clusters, even when plain old create() is called. This is because DFS now internally calls create() through the newly introduced method. By simply changing how the methods are wired internally, we can remove this limitation. We may eventually switch back to the approach in HDFS-617 when the majority of users adopt branch-1 based releases.
