Rohith Sharma K S commented on YARN-8303: ----------------------------------------- thanks [~abmodi] for the patch! I see some issues while testing this patch! # All entity info will be in String. So we need to parse string to int. {code} 2018-11-15 12:25:35,354 WARN impl.YarnClientImpl: Got an error while fetching container report from ATSv2 java.lang.ClassCastException: java.lang.String cannot be cast to java.lang.Integer at org.apache.hadoop.yarn.util.timeline.TimelineEntityV2Converter.convertToContainerReport(TimelineEntityV2Converter.java:97) at org.apache.hadoop.yarn.client.api.impl.AHSv2ClientImpl.getContainers(AHSv2ClientImpl.java:142) at org.apache.hadoop.yarn.client.api.impl.YarnClientImpl.getContainerReportFromHistory(YarnClientImpl.java:922) at org.apache.hadoop.yarn.client.api.impl.YarnClientImpl.getContainers(YarnClientImpl.java:872) at org.apache.hadoop.yarn.client.cli.ApplicationCLI.listContainers(ApplicationCLI.java:1244) at org.apache.hadoop.yarn.client.cli.ApplicationCLI.run(ApplicationCLI.java:487) at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:76) at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:90) at org.apache.hadoop.yarn.client.cli.ApplicationCLI.main(ApplicationCLI.java:123) {code} Looks like similar issue exist all other converter which need to be relooked based on variable type > YarnClient should contact TimelineReader for application/attempt/container > report > --------------------------------------------------------------------------------- > > Key: YARN-8303 > URL: https://issues.apache.org/jira/browse/YARN-8303 > Project: Hadoop YARN > Issue Type: Sub-task > Reporter: Rohith Sharma K S > Assignee: Abhishek Modi > Priority: Critical > Attachments: YARN-8303.001.patch, YARN-8303.002.patch, > YARN-8303.003.patch, YARN-8303.004.patch, YARN-8303.poc.patch > > > YarnClient get app/attempt/container information from RM.
