Hi, My question is what's the difference between the following two settings:
1. mapred.task.default.maxvmem 2. mapred.child.java.opts The first one is used by the TT to monitor the memory usage of tasks, while the second one is the maximum heap space assigned for each task. I want to limit each task to use upto say 100MB of memory. Can I use only #2 ?? Thank you, Mark
