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).
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.
