Oh,I'm a little depressed. Because from the installation instructions of http://tez.apache.org/tez-ui.html,, I saw there were just a few steps . In my tez-site.xml, I configed this: ------------------------------------------------------------------------------------------------------------------------------------------------------------ ... <property> <description>Enable Tez to use the Timeline Server for History Logging</description> <name>tez.history.logging.service.class</name> <value>org.apache.tez.dag.history.logging.ats.ATSHistoryLoggingService</value> </property>
<property> <description>URL for where the Tez UI is hosted</description> <name>tez.tez-ui.history-url.base</name> <value>http://server2:9999/tez-ui/</value> </property> .... .... in yarn-site.xml: ... <property> <description>Indicate to clients whether Timeline service is enabled or not. If enabled, the TimelineClient library used by end-users will post entities and events to the Timeline server.</description> <name>yarn.timeline-service.enabled</name> <value>true</value> </property> <property> <description>The hostname of the Timeline service web application.</description> <name>yarn.timeline-service.hostname</name> <value>server2</value> </property> <property> <description>Enables cross-origin support (CORS) for web services where cross-origin web response headers are needed. For example, javascript making a web services request to the timeline server.</description> <name>yarn.timeline-service.http-cross-origin.enabled</name> <value>true</value> </property> <property> <description>Publish YARN information to Timeline Server</description> <name> yarn.resourcemanager.system-metrics-publisher.enabled</name> <value>true</value> </property> <property> <description>The http address of the Timeline service web application.</description> <name>yarn.timeline-service.webapp.address</name> <value>${yarn.timeline-service.hostname}:8188</value> </property> <property> <description>The https address of the Timeline service web application.</description> <name>yarn.timeline-service.webapp.https.address</name> <value>${yarn.timeline-service.hostname}:2191</value> </property> ... in $TOMCAT_HOME/webapps/tez-ui/scripts/config.js I removed the comment: timelineBaseUrl: 'http://localhost:8188', RMWebUrl: 'http://localhost:8088', --------------------------------------------------------------------------------------------- I started timelineserver and proxyserver: yarn-daemon.sh start timelineserver yarn-daemon.sh start proxyserver While when I visit "http://server2:8080/tez-ui",An error appeared： error code:404,message:error Could not retrive expected data from Timeline server @http://localhost:8188/ws/v1/timeline/TEZ_DAG_ID And also when I attemptted to link tez-ui from yarn UI 8088 Tracking UI history，it was refused. I doubt my configurations, but I was really confused by that error. I need your guidance. Thank you very very much.
