             Summary: Java tests should use unique dirs for minicluster data
                 Key: KUDU-2347
                 URL: https://issues.apache.org/jira/browse/KUDU-2347
             Project: Kudu
          Issue Type: Improvement
          Components: java, test
            Reporter: Todd Lipcon


Currently the Java minicluster just uses TEST_TMPDIR/minicluster-data as a root for its miniclusters. I found some case in which one test failed to clean up that directory and then the next test failed to start because it found existing on-disk data with a different set of master hosts/IPs. It also prevents running multiple instances of the tests in parallel.

We should have the Java tests pass in a unique directory name into the minicluster tool based on the current test being executed to above these collisions.
