Jmeter remote test: .RemoteJMeterEngineImpl_Stub (no security manager: RMI class loader disabled)

Question

I'm new in Jmeter and I try to run distributed tests using this tool with next configuration:

client(master) - Windows 7
- Java version - 1.8.0_92 (7u79 is tried too)
- JMeter, version - 2.13
server(slave) - VM Ubuntu 14 (with using VirtualBox)
- Jave version - 1.7.0_95
- Jmeter version - 2.8.20130705

I've done and tried everything I found in official tutorial and on other posts, including stackoverflow posts, but any success as a result. I get the next error all the time, when I try to run test on server via client:

java.rmi.UnmarshalException: error unmarshalling return; nested exception is: java.lang.ClassNotFoundException: org.apache.jmeter.engine.RemoteJMeterEngineImpl_Stub (no security manager: RMI class loader disabled)

What I've tried in different combinations:

disable firewall on Ubuntu and Windows
using the same subnet
setting hostname in jmeter-server file:

RMI_HOST_DEF=-Djava.rmi.server.hostname=172.29.148.49
creating .java.policy file with granting all permissions in jmeter/bin directory:

grant { permission java.security.AllPermission; };
setting in jmeter-server file:

-Djava.security.policy=file:/usr/share/jmeter/bin/.java.policy
setting all permissions in java.policy file (usr/lib/jvm/java-7-openjdk-amd64/jre/lib/security/java.policy)

In results, when I start jmeter-server on VM Ubuntu, it seems that everything is fine. I get:

log_file=jmeter-server.log java.io.FileNotFoundException: jmeter-server.log     (Permission denied)

Irrelevant.

setting hostname in jmeter-server file:

setting all permissions in java.policy file (usr/lib/jvm/java-7-openjdk-amd64/jre/lib/security/java.policy)

Irrelevant.

Your course of action is baffling. Neither the firewall nor the subnet nor the hostname nor the .policy file nor its name nor its contents have anything whatsoever to do with ClassNotFoundExceptions, either singly or in any combination, and it is mystifying why anybody could ever think otherwise: especially in relation to the security-policy actions, when the error message notes explicitly that a security manager is not installed.

The solution to a ClassNotFoundException is to deploy the class concerned, to the JVM concerned. In this case, the client. Jmeter provides this class in some JAR file and it is required on the CLASSPATH of the client.

Thanks. I've tried your solution and also any results. I'm not very good in Java and Jmeter and maybe it is a reason. My solution was: to use the SAME Jmeter version on client and server. Because default ubuntu Jmeter version is 2.8, I've used it on client too. And it works. Thank you! — Mykola Kovsh, Apr 29 '16 at 10:45
