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:

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

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

Answer 1

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.
