Subject [jira] Commented: (HDFS-1318) HDFS Namenode and Datanode WebUI information needs to be accessible programmatically for scripts
Date Wed, 11 Aug 2010 18:12:17 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1318?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12897360#action_12897360
] 

Suresh Srinivas commented on HDFS-1318:
---------------------------------------

Eli, the goal of HDFS-453 is to provide REST APIs for namenode WebUI. Adding REST interface
is not the goal of this jira. Now that this jira exposes namenode and datanode web UI information,
the JMX added in this jira could be used to provide REST interface or servlet based interface,
more cleanly, without the need to access Namenode internal classes directly.

If REST interface is no longer the goal, HDFS-453 can be closed.

> Currently Namenode and Datanode web page needs to be scraped by scripts to get this information.
Having an interface where this structured information is provided, will help building scripts
around it.
