Relationship of the various RPC timeouts

We now have these system properties [defaults in brackets]:

A. *com.datatorrent.stram.rpc.timeout       [5_000]*
B. *com.datatorrent.stram.rpc.delay.timeout [10_000]*
C. *com.datatorrent.stram.rpc.retry.timeout [30_000]*

We also have the attribute:
D. *HEARTBEAT_TIMEOUT_MILLIS [30_000]*

What, if any, is the expected relationship among these values ?
For example, is it expected that: A <= B <= C <= D ?

Will changing A to a large value like 60_000 and leaving
the others at their defaults cause problems (like containers being
killed while RPC retry is in progress) ?

Thanks for any iinfo on this.
