Subject [jira] [Commented] (HADOOP-9160) Adopt Jolokia as the JMX HTTP/JSON bridge.
Date Sun, 04 Aug 2013 07:43:49 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-9160?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13728795#comment-13728795
] 

Junping Du commented on HADOOP-9160:
------------------------------------

Yes. It is pretty straightforward to mark optional for dependency to get rid of unnecessary
transitive dependency. However, I saw very few practices across HADOOP projects. So we don't
pay much attention on it before or some other reasons (prefer to exclude dependencies)?

> 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.
