Hello,

Can you drop the url:

 spark://master:7077

The url is used when running Spark in standalone mode.

Regards

on EMR </div><div>
</div>hi all
 could anyone assist here?
i am trying to run spark 2.0.0 on an EMR cluster,but i am having issues 
connecting to the master node
So, below is a snippet of what i am doing


sc = SparkSession.builder.master(sparkHost).appName("DataProcess").getOrCreate()

sparkHost is passed as input parameter. that was thought so that i can run the 
script locally
on my spark local instance as well as submitting scripts on any cluster i want


Now i have 
1 - setup a cluster on EMR. 
2 - connected to masternode
3  - launch the command spark-submit myscripts.py spark://master:7077

But that results in an connection refused exception
Then i have tried to remove the .master call above and launch the script with 
the following command

spark-submit --master spark://master:7077   myscript.py  but still i am getting
connectionREfused exception


I am using Spark 2.0.0 , could anyone advise on how shall i build the spark 
session and how can i submit a pythjon script to the cluster?

kr
