Subject Port to open for submitting Spark on Yarn application
Date Mon, 04 Sep 2017 00:50:23 GMT

In case we run Spark on Yarn in client mode, we have firewall for
Hadoop cluster,
and the client node is outside firewall, I think I have to open some ports
that Application Master uses.

I think the ports is specified by "" as document says.

But, according to the source code, is deprecated since 2.0.

Does this mean we do not need to open particular ports of firewall for

Spark on Yarn?
