-----------------------------
Summary: Scheduler UI/Metrics need to consider cases like
non-queue label mappings
Key: YARN-4634
URL: https://issues.apache.org/jira/browse/YARN-4634
Project: Hadoop YARN
Issue Type: Bug
Affects Versions: 2.7.1
Reporter: Sunil G
Assignee: Sunil G
Currently when label-queue mappings are not available, there are few
assumptions taken in UI and in metrics.
In above case where labels are enabled and available in cluster but without any
queue mappings, UI displays queues under labels. This is not correct.
Currently labels enabled check and availability of labels are considered to
render scheduler UI. Henceforth we also need to check whether
- queue-mappings are available
- nodes are mapped with labels with proper exclusivity flags on
This ticket also will try to see the default configurations in queue when
labels are not mapped.
