Alejandro Abdelnur commented on HADOOP-9160:
--------------------------------------------
OK, just went over the comments, my concerns are essentially the same ones that
Todd, Suresh and Allen have raised. I don't think we should introduce yet
another protocol for admin 'write' operations. Admin tools should built on top
of the existing admin interfaces.
> Adopt Jolokia as the JMX HTTP/JSON bridge.

>
> The current JMX HTTP bridge has served its purpose, while a more complete
> solution: Jolokia (formerly Jmx4Perl) has been developed/matured over the
> years.
> Jolokia provides comprehensive JMX features over HTTP/JSON including search
> and list of JMX attributes and operations metadata, which helps to support
> inter framework/platform compatibility. It has first class language bindings
> for Perl, Python, Javascript, Java.
> It's trivial (see demo patch) to incorporate Jolokia servlet into Hadoop HTTP
> servers and use the same security mechanisms.
> Adopting Jolokia will substantially improve the manageability of Hadoop and
> its ecosystem.
