Manikandan R edited comment on YARN-9772 at 9/10/19 4:14 PM: ------------------------------------------------------------- To keep it simple and given the probability of having same names for parent and leaf queues is very less, Should we extend the duplicates check (as of now, it does only for leaf queues) to parent queues as well? [~sunilg] [~wangda] [~weiweiyagn666] [~eepayne] Please share your thoughts. was (Author: maniraj...@gmail.com): To keep it simple, Should we extend the duplicates check (as of now, it does only for leaf queues) to parent queues as well?

After parsing all the queues, map count > should be 7, but it is 6. Any reference to queue "root.a.b" in code path is > nothing but "root.a.d.b" object. Since > {{CapacitySchedulerQueueManager#getQueues}} has been used in multiple places, > will need to understand the implications in detail. For example, > {{CapapcityScheduler#getQueue}} has been used in many places which in turn > uses {{CapacitySchedulerQueueManager#getQueues}}. cc [~eepayne], [~sunilg] -- This message was sent by Atlassian Jira (v8.3.2#803003) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
