Steve Loughran commented on YARN-7747: -------------------------------------- * is there a way to get that UI URL back? If it's not there already? * are there tests which look @ this, e.g. issue a GET or two? > YARN UI is broken in the minicluster > ------------------------------------- > > Key: YARN-7747 > URL: https://issues.apache.org/jira/browse/YARN-7747 > Project: Hadoop YARN > Issue Type: Bug > Affects Versions: 3.0.0 > Reporter: Gera Shegalov > Assignee: Gera Shegalov > Priority: Major > Attachments: YARN-7747.001.patch, YARN-7747.002.patch > > > YARN web apps use non-injected instances of GuiceFilter, i.e. instances > created by Jetty as opposed by Guice itself. This triggers the [call > path|https://github.com/google/guice/blob/master/extensions/servlet/src/com/google/inject/servlet/GuiceFilter.java#L251] > where the static field {{pipeline}} is used instead of the instance field > {{injectedPipeline}}. However, besides GuiceFilter instances created by > Jetty, each Guice module generates them as well. On the injection call path > this static variable is updated by each instance. Thus if there are multiple > modules as it happens to be the case in the minicluster the one loaded last > ends up defining the filter pipeline for all Jetty instances. In the > minicluster case this is the nodemanager UI > -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
