Subject [jira] [Created] (YARN-6546) SLS is slow while loading 10k queues
Date Tue, 02 May 2017 18:36:04 GMT
Yufei Gu created YARN-6546:

             Summary: SLS is slow while loading 10k queues
                 Key: YARN-6546
                 URL: https://issues.apache.org/jira/browse/YARN-6546
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: scheduler-load-simulator
            Reporter: Yufei Gu
            Assignee: Yufei Gu

It takes a long time (more than 10 minutes) to load 10k queues in SLS. The problem should
be in {{com.codahale.metrics.CsvReporter}} based on the result from profiler. SLS creates
14 .csv files for each leaf queue. It is not necessary to log information for inactive queues.
