Subject [jira] Updated: (CHUKWA-515) REST API for Agent
Date Tue, 14 Sep 2010 17:15:32 GMT

     [ https://issues.apache.org/jira/browse/CHUKWA-515?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Bill Graham updated CHUKWA-515:
-------------------------------

    Attachment: CHUKWA-515-4.patch

Here's patch 4, which uses Jersey. The only functional change from the last one, is that the
add command now takes an optional viewType querystring just like the get command. The default
for both add and get is to return XML, but text is also supported. I've also added the ability
to inject other user-developed servlets into the REST server (similar to what's done on the
collector) by setting the {{chukwaAgent.http.rest.controller.packages}} config. This appends
to the default {{org.apache.hadoop.chukwa.datacollection.agent.rest}} package.

> Develop a REST interface for the Agent to expose Adaptor CRUD operations.
> * Request URI:
> {noformat}
> GET /rest/v1/adaptor HTTP/1.0
> {noformat}
> * For now I'm shooting for the XML and plain text response, but ultimately we can support
optional params:
> {noformat}
> viewType=[json|xml|text] (default is XML?)
> {noformat}
> I'm planning on using Jetty similar to how the collector does. We could have some common
code that delegates requests to different handlers based on the URI. The current telnet interface
will remain as-is.
