Haibo Chen commented on YARN-6733: ---------------------------------- I have a few questions on the Tez use case. 1) Is the sub_application going to have similar schema as ApplicationTable? 2) Are nodes in a Tez DAG all YARN applications? If so, can't Tez write to ApplicationTable with the doAs user? > Add table for storing sub-application entities > ---------------------------------------------- > > Key: YARN-6733 > URL: https://issues.apache.org/jira/browse/YARN-6733 > Project: Hadoop YARN > Issue Type: Sub-task > Components: timelineserver > Reporter: Vrushali C > Assignee: Vrushali C > > After a discussion with Tez folks, we have been thinking over introducing a > table to store sub-application information. > For example, if a Tez session runs for a certain period as User X and runs a > few AMs. These AMs accept DAGs from other users. Tez will execute these dags > with a doAs user. ATSv2 should store this information in a new table perhaps > called as "sub_application" table. > This jira tracks the code changes needed for table schema creation. > I will file other jiras for writing to that table, updating the user name > fields to include sub-application user etc. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
