adoroszlai opened a new pull request #621: HDDS-3106. Intermittent timeout in TestOzoneManagerDoubleBufferWithOMResponse#testDoubleBuffer URL: https://github.com/apache/hadoop-ozone/pull/621 ## What changes were proposed in this pull request? Generate volume name using `UUID.randomUUID()` instead of a 5-char random alphabetic string. Checked the output of some timed out executions of the test, and found that the number of volumes created is less than expected: ``` $ grep -c 'created volume' [fs]* failed1:1054 failed2:1109 success:1114 ``` I think this is due to conflicts in random names (ie. same name is generated twice). https://issues.apache.org/jira/browse/HDDS-3106 ## How was this patch tested? Regular CI with all checks: https://github.com/adoroszlai/hadoop-ozone/runs/479415494
