Summary: TASK: Fix JobQueue's job state-related bug
Key: HELIX-783
URL: https://issues.apache.org/jira/browse/HELIX-783
Project: Apache Helix
Issue Type: Improvement
Reporter: Hunter L
Assignee: Hunter L
The bug was observed in TestTaskRebalancerStopResume:stopAndResumeNamedQueue(),
which was being unstable. It was observed that for JobQueues with multiple
jobs, the second job would get marked as IN_PROGRESS even though the first job
hadn't completed/failed, especially when the queue was being stopped and
resumed. This was due to a bug in getIncompleteJobCount() because it was not
counting jobs in STOPPING state. This was fixed and another check was added
right before JobDispatcher marks a job as STOPPED so that it would not mark it
STOPPED if the job state is NOT_STARTED. Changelist: 1. Fix
getIncompleteJobCount() 2. Add a check so that we don't mark NOT_STARTED jobs
as STOPPED
