Subject [jira] [Updated] (YARN-3087) [Aggregator implementation] the REST server (web server) for per-node aggregator does not work if it runs inside node manager
Date Thu, 26 Feb 2015 05:29:05 GMT

Li Lu updated YARN-3087:
------------------------
    Attachment: YARN-3087-022515.patch

I've just updated my patch. This patch is rebased to the latest YARN-2928 branch. Other than
all changes happened in the previous version, I added support functions in our object model
classes for REST calls. I also added a static user web filter to the newly created web server.
This patch passed the (newly added, in YARN-3240) TestTimelineServiceClientIntegration.

> This is related to YARN-3030. YARN-3030 sets up a per-node timeline aggregator and the
associated REST server. It runs fine as a standalone process, but does not work if it runs
inside the node manager due to possible collisions of servlet mapping.
