I want to have something to clarify, for the max task slots, are these places to check: 1. hadoop-site.xml 2. the specific job's job.conf which can be retrieved though the job, for example, logs/job_200904212336_0002_conf.xml
Any other place to limit the task map counts? In my case, it's strange, because I set 10 for " mapred.tasktracker.map.tasks.maximum", and I check the job's conf is also 10, but actual hadoop is just using 2 map jobs.
