> - 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.
