Running the UT didn't give a NPE, however the unmodified test case caused FS init failure with: {code:java} org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.AllocationConfigurationException: Could get past last queue placement rule without assigning {code} This is expected, as the rule without create flag is not terminal. But the NPE didn't occur. was (Author: bteke): [~wilfreds], [~snemeth] what do we expect from YARN-8951?

However the default queue does not need to exist. We have two possible > cases which we should handle: > * Based on the placement rule "Default" the name for the default queue might > not be default and it should be created with a different name > * There might not be a "Default" placement rule at all which removes the need > to create the queue. > We should leave the creation of the default queue to the point in time that > we can assess if it is needed or not. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
