             Summary: [utest] tests unable to write system tmp directory
                 Key: CASSANDRA-14791
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-14791
             Project: Cassandra
          Issue Type: Task
          Components: Testing
            Reporter: Jay Zhuang


Some tests are failing from time to time because it cannot write to directory {{/tmp/}}:

 I guess it's because some Jenkins slaves don't have proper permission set. For slave {{cassandra16}}, the tests are fine:
