Sangjin Lee commented on YARN-3087: ----------------------------------- PerNodeTimelineAggregatorsAuxService contains a main method, and as such it can be started directly. An alternative is to use the unit test (TestPerNodeTimelineAggregatorsAuxService.testLaunch) to bring it up. You might need to insert sleep or set a breakpoint to keep it up, however. > [Aggregator implementation] the REST server (web server) for per-node > aggregator does not work if it runs inside node manager > ----------------------------------------------------------------------------------------------------------------------------- > > Key: YARN-3087 > URL: https://issues.apache.org/jira/browse/YARN-3087 > Project: Hadoop YARN > Issue Type: Sub-task > Components: timelineserver > Reporter: Sangjin Lee > Assignee: Li Lu > Fix For: YARN-2928 > > Attachments: YARN-3087-022315.patch, YARN-3087-022515.patch, > YARN-3087-022615.patch > > > 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. > Exception: > {noformat} > org.apache.hadoop.yarn.webapp.WebAppException: /v2/timeline: controller for > v2 not found > at org.apache.hadoop.yarn.webapp.Router.resolveDefault(Router.java:232) > at org.apache.hadoop.yarn.webapp.Router.resolve(Router.java:140) > at org.apache.hadoop.yarn.webapp.Dispatcher.service(Dispatcher.java:134) > at javax.servlet.http.HttpServlet.service(HttpServlet.java:820) > at > com.google.inject.servlet.ServletDefinition.doService(ServletDefinition.java:263) > at > com.google.inject.servlet.ServletDefinition.service(ServletDefinition.java:178) > at > com.google.inject.servlet.ManagedServletPipeline.service(ManagedServletPipeline.java:91) > at > com.google.inject.servlet.FilterChainInvocation.doFilter(FilterChainInvocation.java:62) > at > com.sun.jersey.spi.container.servlet.ServletContainer.doFilter(ServletContainer.java:900) > at > com.sun.jersey.spi.container.servlet.ServletContainer.doFilter(ServletContainer.java:834) > at > com.sun.jersey.spi.container.servlet.ServletContainer.doFilter(ServletContainer.java:795) > ... > {noformat} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
