Github user mateiz commented on the pull request: https://github.com/apache/spark/pull/892#issuecomment-45175977 I see, we might be able to fix that as a separate issue. We could count pendingTasksWithNoPrefs as being at a "special" level we try only after we try the real locality levels. But that seems independent of this patch, maybe you can report it as a separate JIRA.
