Re: Time taken for starting AMRMClientAsync
It is just creating a connection to RM and shouldn't take that long. Can you please file a ticket so that we can look at it?

JVM class loading overhead is one possibility but 1 sec is a bit too much.

Is there a way to reduce it, I mean does it depend on any of the interval parameters or so in configuration files? I have tried reducing the value of the first argument below from 1000 to 100 seconds also, but that doesn't help.
