Subject [jira] Commented: (HADOOP-5722) HTTP metrics interface enable/disable must be configurable
Date Fri, 24 Apr 2009 23:39:30 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-5722?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12702624#action_12702624
] 

Robert Chansler commented on HADOOP-5722:
-----------------------------------------

What about making the list of deployed servlets configurable? That way an administrator could
choose any list of favorites, and no individual servle would have to test whether is was enabled
or not.

> HADOOP-5469 added a convenient end-run around JMX authentication by revealing the same
metrics over HTTP. That's cool, but we need to secure all accesses to our Hadoop cluster,
so while this may be enabled by default, we need some configurable way to disable the unauthenticated
port.
