      Description

      NodeManagers never serve logs for completed applications. If log-aggregation is not enabled, in the interim, due to bugs like YARN-162, this is a serious problem for users as logs are necessarily not available.

      We should let nodes serve logs directly if YarnConfiguration.LOG_AGGREGATION_ENABLED is set. This should be okay as NonAggregatingLogHandler can retain logs upto YarnConfiguration.NM_LOG_RETAIN_SECONDS.
