Hi, after upgraded to Hadoop 2 (yarn), I found that 'mapred.jobtracker.taskScheduler.maxRunningTasksPerJob' no longer worked, right?
One workaround is to use queue to limit it, but it's not easy to control it from job submitter. Is there any way to limit the concurrent running mappers per job? Any documents or discussions before? BTW, any way to search this mailing list before I post a new question? Thanks very much.
