Spark Master IP configuration in Azure VM

Question

I am setting up standalone Spark cluster in Azure VM. I want to run Spark master with Azure VM's public IP not with VM's hostname, so that I can access from other VM.

Spark version: spark-2.2.0-bin-hadoop2.7

I have created new file "spark-env.sh" under conf folder and added export SPARK_MASTER_HOST=x.x.x.x

Start master sbin>./start-master.sh

I am getting below mentioned error. Spark master is not started.

How to set public IP address to Spark Master ?

For SPARK_MASTER_HOST, you should use VM's private IP or 0.0.0.0, you could not enter VM's public IP, if you do it, you will get the error log.

Now, you want to access Spark Master by public IP, you need open port 7077-7093(not sure, depends on your service) on Azure NSG and VM's firewall.
