We'd like to check the values of an attirbute on all cluster nodes. Is there any quick way to do so?

During the startup of your own JMX MBean service you first have to register it with HAPartition
using registerRPCHandler method in HAPartition [1]. Provide a service name and your own
MBean object as parameters.

When checking a value of an attribute of your mbean in the whole cluster you would invoke
HAPartition.callMethodOnCluster together with service name parameter provided for
registerRPCHandler method. You have to expose this attribute as an operation

However, it would be more convenient to just use getter or setter. thanks,
