Capacity scheduler's implementation of getJobs modifies the list of running
jobs inadvertently
----------------------------------------------------------------------------------------------
Key: HADOOP-4274
URL: https://issues.apache.org/jira/browse/HADOOP-4274
Project: Hadoop Core
Issue Type: Bug
Components: contrib/capacity-sched
Affects Versions: 0.19.0
Reporter: Hemanth Yamijala
Assignee: Hemanth Yamijala
Priority: Blocker
Fix For: 0.19.0
The implementation of the {{getJobs}} API gets the running jobs queue from the
{{JobQueueManager}}. If it is not null, it appends waiting jobs to the list and
returns that. This modifies the original list of running jobs and can affect
the scheduler drastically.
