Ah, forgot the -verbose option. Thanks Andrew. That is very helpful.

The answer is actually yarn-client. A quick way to find out:
$ bin/spark-shell --master yarn --verbose
>From the system properties you can see spark.master is set to "yarn-client." 
>From the code, this is because args.deployMode is null, and so it's not equal 
>to "cluster" and so it falls into the second "if" case you mentioned:

if (args.deployMode != "cluster" && args.master.startsWith("yarn")) {
  args.master = "yarn-client"}

Does anyone know if:
./bin/spark-shell --master yarn 
is running yarn-cluster or yarn-client by default?

Base on source code:







./core/src/main/scala/org/apache/spark/deploy/SparkSubmit.scala


if (args.deployMode == "cluster" && args.master.startsWith("yarn")) {

  args.master = "yarn-cluster"
}
if (args.deployMode != "cluster" && args.master.startsWith("yarn")) {

  args.master = "yarn-client"














}

It looks like the answer is yarn-cluster mode.
I want to confirm this with the community, thanks.
