Subject [jira] Commented: (HADOOP-6977) Herriot daemon clients should vend statistics
Date Thu, 07 Oct 2010 04:54:31 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6977?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12918786#action_12918786
] 

Konstantin Boudnik commented on HADOOP-6977:
--------------------------------------------

bq. In fact, we can enable JMX ( with specific port number ) by modifying command specific
options
I think this is valid and I'll make the change to look for JMX specific parameters in a daemon
specific options (i.e. HADOOP_NAMENODE_OPTS) as well as in HADOOP_OPTS. That should cover
all the bases.

Typo: check, good catch.

FinderTest was an example of loops optimization and isn't a part of the patch.

> The HDFS web user interface serves useful information through dfshealth.jsp and dfsnodelist.jsp.
> The Herriot interface to Hadoop cluster daemons would benefit from the addition of some
way to channel metics information.
