> Mini cluster test flakiness
> ---------------------------
>
> Key: HDFS-16740
> URL: https://issues.apache.org/jira/browse/HDFS-16740
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: hdfs, test
> Affects Versions: 3.4.0, 3.3.5
> Reporter: Steve Vaughan
> Assignee: Steve Vaughan
> Priority: Major
> Labels: pull-request-available
>
> Mini clusters used during HDFS unit tests are reporting test failures that do
> not appear to be directly related to submitted changes. The failures are the
> result of either interactions between tests run in parallel, or tests which
> share common disk space for tests. In all cases, the tests can be run
> individually serially without any errors. Addressing this issue will
> simplify future submissions by eliminating the confusion introduced by these
> unrelated test failures.
> We can apply lessons recently from TestRollingUpgrade, which was recently
> patched to unblock a recent submission. The fixes involved changing the HDFS
> configuration to use temporary disk space for each individual tests, and
> using try-with-resources to ensure that clusters were shutdown cleanly.
