Subject [jira] Commented: (HADOOP-349) Allow info server to be turned off/on by conf file
Date Sat, 08 Jul 2006 07:45:30 GMT
    [ http://issues.apache.org/jira/browse/HADOOP-349?page=comments#action_12419844 ] 

Doug Cutting commented on HADOOP-349:
-------------------------------------

What is the problem with running a Jetty-based daemon from within Tomcat?

It sounds like you'd like to package daemons as war files.  So, in this scheme, there would
be separate namenode, datanode, tasktracker and jobtracker war file, since each exposes a
distinct web interface, right?  That's a larger change to Hadoop than simply disabling the
jetty daemons, since Hadoop sometimes stores application state in the servlet context, etc.

Short of that, you could simply package the datanode as a war file, but permit it to start
its own daemon for it's web interface on a different port.  Is that so horrible?

> Since I am using hadoop within my own servlet which is not Jetty, it would be nice to
not have to need Jetty to run my servlet. As such I propose adding an if statement/donf setting
at FSNamesystem:171 as such         
> if(conf.getBoolean("dfs.info.active",true)){
>             this.infoPort = conf.getInt("dfs.info.port", 50070);
>             this.infoServer = new StatusHttpServer("dfs", infoPort, false);
>             this.infoServer.start();
> }
