[jira] [Created] (TEZ-2806) TestContainerReuse flaky

Siddharth Seth created TEZ-2806:
-----------------------------------

             Summary: TestContainerReuse flaky
                 Key: TEZ-2806
                 URL: https://issues.apache.org/jira/browse/TEZ-2806
             Project: Apache Tez
          Issue Type: Bug
    Affects Versions: 0.5.0
            Reporter: Siddharth Seth


TestContainerReuse and TestTaskScheduler use a mechanism to get notified when a scheduler run completes.

However, there seems to be a race where a scheduling run may already have started, after which a request is made for an allocation / containers are allocated. The request ends up being skipped in the current scheduling run; meanwhile the notification mechanism signals completion.
