             Summary: s3guard tool tests aren't isolated; can't run in parallel
                 Key: HADOOP-14125
                 URL: https://issues.apache.org/jira/browse/HADOOP-14125
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: fs/s3, test
    Affects Versions: HADOOP-13345
            Reporter: Steve Loughran


The {{S3GuardToolTestBase}} don't parallelize and break other tests. This can surface if you
do a full run with -Ds3guard and -Ddynamo.

# many of the test paths they create are being requested with absolute paths, e.g {{"/test-diff"}}.
# the base class doesn't  set up a per-forked-JUnit-test runner path in the bucket
# and there's no cleanup at the end of each test case; teardown() is empty.

Ideally, the tests should be made child classes of  {{AbstractS3ATestBase}}, with its post-run
cleanup, If that can't be done, then the tests must 
# use {{S3ATestUtils.createTestPath(super.getTestPath())} to create the base test path
# clean up that dir in teardown if the FS instance is non-null. {{ContractTestUtils.cleanup()}}
can do this.

If it happens that the tests cannot run in parallel with others, then the build must be changed
to exclude them from the parallel test run phase & include them in the serialized section.
