Sean Owen updated SPARK-23002:
------------------------------
Priority: Minor (was: Major)
Good point, I had never really noticed that, but except in local most where
it's always localhost, it does seem to use the IP address for some reason. I
traced through the code and wasn't exactly sure where this comes from. I think
it might be in CoarseGrainedSchedulerBackend, where it decides the executor
address like:
{code}
val executorAddress = if (executorRef.address != null) {
executorRef.address
} else {
context.senderAddress
}
{code}
I don't know if [~vanzin] has time to look at this, but might have touched the
relevant code last.
