Resolution: Fixed
Status: Resolved (was: Patch Available)
> Handle the scenario when 'capacity-scheduler' configs is passed in as
> dictionary to Stack Advisor (generally on 1st invocation) in order to create
> 'llap' queue for Hive Server Interactive.

> - The 1st call to SA gets capacity-scheduler configs as dictionary compared
> to "/n" separated single string of all the configs in subsequent calls.
> * 1st invocation, passed-in capacity-scheduler looks like :
> {code}
> "capacity-scheduler" : {
> "properties" : {
> "capacity-scheduler" : "null",
> "yarn.scheduler.capacity.root.accessible-node-labels" : "*",
> "yarn.scheduler.capacity.maximum-am-resource-percent" : "1",
> "yarn.scheduler.capacity.root.acl_administer_queue" : "*",
> "yarn.scheduler.capacity.queue-mappings-override.enable" :
> 'false',
> "yarn.scheduler.capacity.root.default.capacity" : "100",
> "yarn.scheduler.capacity.root.default.user-limit-factor" : "1",
> "yarn.scheduler.capacity.root.queues" : "default",
> "yarn.scheduler.capacity.root.capacity" : "100",
> "yarn.scheduler.capacity.root.default.acl_submit_applications" :
> "*",
> "yarn.scheduler.capacity.root.default.maximum-capacity" : "100",
> "yarn.scheduler.capacity.node-locality-delay" : "40",
> "yarn.scheduler.capacity.maximum-applications" : "10000",
> "yarn.scheduler.capacity.root.default.state" : "RUNNING"
> }
> },
> {code}
> * subsequent invocations gets capacity-schdeuler as:
> {code}
> "capacity-scheduler": {
> "properties": {
> "capacity-scheduler":
> "yarn.scheduler.capacity.root.queues=default\n"
>
> "yarn.scheduler.capacity.root.default.user-limit-factor=1\n"
>
> "yarn.scheduler.capacity.root.default.state=RUNNING\n"
>
> "yarn.scheduler.capacity.root.default.maximum-capacity=100\n"
>
> "yarn.scheduler.capacity.root.default.capacity=100\n"
>
> "yarn.scheduler.capacity.root.default.acl_submit_applications=*\n"
>
> "yarn.scheduler.capacity.root.capacity=100\n"
>
> "yarn.scheduler.capacity.root.acl_administer_queue=*\n"
>
> "yarn.scheduler.capacity.root.accessible-node-labels=*\n"
>
> "yarn.scheduler.capacity.node-locality-delay=40\n"
>
> "yarn.scheduler.capacity.maximum-applications=10000\n"
>
> "yarn.scheduler.capacity.maximum-am-resource-percent=1\n"
>
> "yarn.scheduler.capacity.queue-mappings-override.enable=false\n"
> }
> },
> {code}
> - Therefore, SA fails to create the 'llap' queue for Hive Server Interactive,
> as SA knows to handle only the 2nd case.
> - This specific issue was seen with while deploying cluster with Blueprints.
