GeorgeJahad opened a new pull request, #4592:
URL: https://github.com/apache/ozone/pull/4592

   
   ## What changes were proposed in this pull request?
   
   This test was flaky because one thread trys to read the log output from 
another thread before the log has been generated.
   
   I confirmed this by hitting a breakpoint on the assertion failure, then 
looking at the log and seeing that it had subsequently been updated by another 
thread.
   
   The fix is the to poll the log for a few seconds until it is updated to the 
expected contents.
   
   ## What is the link to the Apache JIRA
   
   https://issues.apache.org/jira/browse/HDDS-8355
   
   ## How was this patch tested?
   
   Without the fix, I was able to reproduce the problem by running the test 
class 5 times repeatedly in intellij.
   
   With the fix, I was unable to reproduce the problem after running it in 
intellij 50 times.
   
   I also ran the CI 25 times without fail.
