Vinay commented on HADOOP-10136:
--------------------------------
bq. In this case we can change the default port right ?
We could change default ports to some other range. But these ports are there
from very long time. I feel changing needs to be mentioned as incompatible.
{quote}In case of JMX even if we need to configure it is not possible.
So i think better to keep this JMX server as an option.{quote}
Yes.
> Custom JMX server to avoid random port usage by default JMX Server

> If any of the java process want to enable the JMX MBean server then
> following VM arguments needs to be passed.
> {code}
> -Dcom.sun.management.jmxremote
> -Dcom.sun.management.jmxremote.port=14005
> -Dcom.sun.management.jmxremote.local.only=false
> -Dcom.sun.management.jmxremote.authenticate=false
> -Dcom.sun.management.jmxremote.ssl=false{code}
> But the issue here is this will use one more random port other than 14005
> while starting JMX.
> This can be a problem if that random port is used for some other service.
> So support a custom JMX Server through which random port can be avoided.
