The UI pulls it from nimbus using the thrift API.
https://github.com/apache/storm/blob/master/storm-core/src/storm.thrift#L611
is the API definition, although it may be different depending on which version
of storm you are using.
getTopologyInfo has executors in it, and each of them has a scheduling
including host and port. Although the scheduling might be null if they are
being rescheduled. - Bobby

Greetings,
I am running storm on two VMs(ubuntu 16.04, 2GB Ram) on my laptop(in
distributed mode). The issue is that the VM runs out of RAM as soon as I start
a simple(but with a large number of workers) topology.
Actually I am interested only in the executor-Id to Slot-Id mapping from the
Default Scheduler and I need it real quick as I am on a strict deadline.
Getting it through the UI is near impossible as browsers take up too much RAM.
Shifting to a different environment isn't really feasible. Can I get the
mapping from say a file? Or where does the UI pick it up from?
