Subject Re: Distributed Load testing Problem
Date Wed, 13 Mar 2019 20:01:01 GMT
Two things you might have to check

1) keystore
since JMeter 4.0 you have to either configure a keystore for RMI, or
disable rmi over ssl
(see https://jmeter.apache.org/usermanual/remote-test.html#setup_ssl)

2) Is the rmi port (default 1099) open?
>From the master, does telnet <ip of one of the slaves> 1099 work, or do you
get a "connection refused"?
>From one of the slaves, does telnet <ip of the master> 1099 work?

best regards,
Ivan
