Unable to bind Jolokia JVM agent with my PID

Question

We are unable to attach the JVM agent to pid of flink process with jmx enabled on it.
We are using java 1.8, java hotspot is enabled, and doing it with the same UID (sudo) only.
Also there are no other agents attached to that process.
Also we have restarted the process n number of times and tried that.
when i give list option with the agent it shows this process in the list.
Yet we are not able to bind the JVM agent with that process.

Error:

Invocation Target class com.sun.tools.attach.VirtualMachine command:start : null
Invocation Target class com.sun.tools.attach.VirtualMachine command:status : null

Are you really sure that the process you want attach to is running as root ? Remember, you must be the very exact user under which the process is running. Being root via sudo is not good enough (as mentioned in the docs). — Roland Huß, Feb 01 '17 at 22:40
By running the jolokia as the same user as my process is running with, i was able solve the issue. — Aakarshit Naga Sai Batchu, Apr 25 '17 at 09:33

It seems you're using the JRE which doesn't have required attach API in its runtime class path ? Try launching the agent installer with the full JDK java executable, or add tools.jar to the class path.
