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

             Summary: Mapreduce failure when using Hadoop 2.7.5
                 Key: HDDS-1525
                 URL: https://issues.apache.org/jira/browse/HDDS-1525
             Project: Hadoop Distributed Data Store
          Issue Type: Bug
          Components: Ozone Filesystem
    Affects Versions: 0.4.0
            Reporter: Sammi Chen
         Attachments: teragen.log

Integrate Ozone(0.4 branch) with Hadoop 2.7.5, "hdfs dfs -ls /" can pass, while teragen  failed. 

When add  -verbose:class to java options, it shows that class KeyProvider is loaded twice by different classloader while it is only loaded once when execute  "hdfs dfs -ls /" 

All jars under share/ozone/lib are added into hadoop classpath except ozone file system current lib jar.
