Ashish Doneriya created YARN-6279:
-------------------------------------
Summary: Scheduler rest api JSON is not providing all child queues
names
Key: YARN-6279
URL: https://issues.apache.org/jira/browse/YARN-6279
Project: Hadoop YARN
Issue Type: Bug
Components: api, fairscheduler, scheduler
Affects Versions: 2.4.1
Environment: Ubuntu 14.04, 7.7 GiB, i5, 3.4GHz x 4, 64-bit
Reporter: Ashish Doneriya
When I hit rest api /ws/v1/cluster/scheduler to get the JSON file. Its gave me
all child queues information, But it didn't gave me all information about child
queues of child queues. It displays information of only one sub child queue.
While in xml format there is no such problem.
I'm providing the xml and json outputs..
