------------------------------
Summary: [TASK] Fix purgeExpiredJobs() so that jobs whose removal
has failed do not get removed from DAG
Key: HELIX-743
URL: https://issues.apache.org/jira/browse/HELIX-743
Project: Apache Helix
Issue Type: Improvement
Reporter: Hunter L
Previously, even if the job removal had failed, Task Framework would go ahead
and remove the job from the DAG. This would cause some ZNodes to be left over
and never be cleaned up at next purge time. Changelist: 1. Keep track of jobs
whose removal failed and remove them from expiredJobs so that next call to
purgeExpiredJobs(), the job would be included in expiredJobs again and removal
would be tried again.
