Daryn Sharp created HDFS-6948:
---------------------------------

             Summary: DN rejects blocks if it has older UC block
                 Key: HDFS-6948
                 URL: https://issues.apache.org/jira/browse/HDFS-6948

          Issue Type: Bug
    Affects Versions: 2.0.0-alpha, 3.0.0

DNs appear to always reject blocks, even with newer genstamps, if it already has a UC copy in its tmp dir.

exists in state TEMPORARY and thus cannot be created{noformat}
