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

             Summary: FileContextMainOperationsBaseTest should randomize the root dir 
                 Key: HADOOP-8766
                 URL: https://issues.apache.org/jira/browse/HADOOP-8766
             Project: Hadoop Common
          Issue Type: Bug
          Components: test
    Affects Versions: 2.0.0-alpha
            Reporter: Eli Collins


FileContextMainOperationsBaseTest should randomize the name of the root directory it creates. It currently hardcodes LOCAL_FS_ROOT_URI to {{/tmp/test}}.

This causes the job to fail if it clashes with another jobs that also uses that path. Eg
