Subject Cannot connect to standalone spark cluster
Date Fri, 09 Oct 2015 21:37:34 GMT
Hi,
I'm trying to run a java application that connects to a local standalone
spark cluster.  I start the cluster with the default configuration, using
start-all.sh.  When I go to the web page for the cluster, it is started ok. 
I can connect to this cluster with SparkR, but when I use the same master
URL to connect from within Java, I get an error message.  

I'm using Spark 1.5.

Here is a snippet of the error message:

 ReliableDeliverySupervisor: Association with remote system
