Subject [jira] [Commented] (HBASE-9404) Create Monitor Daemon instead of current web ui's
Date Sat, 31 Aug 2013 11:00:52 GMT

    [ https://issues.apache.org/jira/browse/HBASE-9404?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13755480#comment-13755480
] 

Andrew Purtell commented on HBASE-9404:
---------------------------------------

Francis Liu was also talking about separating out the presented information according to the
privileges of the requester. That made some sense but at the same time the UIs currently still
need to be protected from arbitrary access so users don't mount an accidental (or otherwise)
denial of service attack. A separate monitor will be good for this too.

> It's hard to get designers and front end developers to iterate on our web ui, partly
because it's not well separated, and partly because it's in java jsp/jamon.  It would be awesome
to have something like Accumulo's monitor.
> Have all of the current daemons just publish everything through json and remove the current
UI.  Then we can separate the ui out into a monitor daemon that's just UI.
> This would do a couple of things:
> * force us to publish everything that's interesting though the 
> metrics system. (Lots of stuff is there but some stuff isn't there.)
> * remove a lot of resources from our hbase-server jar.
> * make it easier to add graphing other features to the ui.
> * allow us to remove some things from the rs -> master heart beat.
> * encourage front end developers to get involved (wishful ?)
