Tamas Domok updated YARN-10891:
-------------------------------
Description:
Add max-parallel-apps
https://hadoop.apache.org/docs/stable/hadoop-yarn/hadoop-yarn-site/ResourceManagerRest.html#Cluster_Scheduler_API
Maximum number of applications that can run at the same time. Unlike to
{{maximum-applications}}, application submissions are _not_ rejected when this
limit is reached. Instead they stay in {{ACCEPTED}} state until they are
eligible to run. This can be set for all queues with
{{yarn.scheduler.capacity.max-parallel-apps}} and can also be overridden on a
per queue basis by setting
{{yarn.scheduler.capacity.<queue-path>.max-parallel-apps}}. Integer value is
expected. By default, there is no limit.
was:
Extend QueueInfo with the max-parallel-apps property, so the clients can query
the queue basis max-parallel-apps property.
