[GitHub] [ozone] adoroszlai opened a new pull request #2339: HDDS-5348. Pipeline creator may miss one-shot run

[GitBox <gi...@apache.org>]

adoroszlai opened a new pull request #2339:
URL: https://github.com/apache/ozone/pull/2339


   ## What changes were proposed in this pull request?
   
   If `BackgroundPipelineCreatorV2` tries to trigger one-shot run while pipeline creation is in progress (before entering `wait()`), then its `notifyAll()` call is lost.  This can result in unnecessary wait, as it will only check if it needs to run after the wait is over.
   
   I think this may contribute to tests timing out waiting for SCM safemode exit.
   
   This change adds a simple check for one-shot run flag before entering wait.
