> {{TestMiniChaosOzoneCluster}} runs load generator on a cluster for supposedly 1 minute,
but it may run indefinitely until JVM crashes due to OutOfMemoryError.
> In 0.4.1 nightly build it crashed 29/30 times (and no tests were executed in the remaining
one run due to some other error).
> Latest:
> https://github.com/elek/ozone-ci/blob/3f553ed6ad358ba61a302967617de737d7fea01a/byscane/byscane-nightly-wggqd/integration/output.log#L5661-L5662
> When it crashes, it leaves GBs of data lying around.
> HDDS-1952 disabled this test in CI runs.  It can still be run manually (eg. {{mvn -Phdds
-pl :hadoop-ozone-integration-test -Dtest=TestMiniChaosOzoneCluster test}}).  The goal of
this task is to investigate the root cause of the runaway nature of this test.
