I setup a new Spark cluster. My worker node is dying with the following
exception.
Caused by: java.util.concurrent.TimeoutException: Futures timed out after
[120 seconds]

scala.concurrent.impl.Promise$DefaultPromise.result(Promise.scala:223)

Any ideas what's wrong? This is happening both for a spark program and spark
shell.
