Unable to launch slave in JMeter 4.0 - jmeter

Question

I want to do the JMeter Master Slave setup in JMeter 4.0 in Windows OS.
I have done the following change in the jmeter-server file.
RMI_HOST_DEF=-Djava.rmi.server.hostname=10.304.61.62
To launch the slave I execute the following command from the bin folder
jmeter-server
This is working in JMeter 3.1. But getting the following error in JMeter 4.0
ERROR o.a.j.JMeter: An error occurred:
java.rmi.server.ExportException: Listen failed on port: 0; nested exception is:

Answer 1

According to Setting Up SSL chapter of the Remote Testing JMeter User Manual entry you need to do one of the following things:
If you want to use secure communication between master and slaves you need to launch create-rmi-keystore script (it's located in "bin" folder of your JMeter installation) - it will produce the required rmi_keystore.jks file.
If you don't want to use secure communication between master and slaves you can add the next line to user.properties file
server.rmi.ssl.disable=true
JMeter restart will bre required to pick the property up
No matter of the approach you will have to implement either 1 or 2 on master and all the slaves
The above answer is based on JMeter Distributed Testing with Docker article.
