Hi everyone, Is it possible to configure Hadoop's TaskTracker in a way that it shutdown itself once being idle (no task to run) for a configurable amount of time? I guess it is not possible in current implementation. This feature is very useful in situations (like of ours) where a MapReduce jobs can be scheduled by a batch processing system. In other words, the ability to schedule and run a single MapReduce job on a computing cluster that is also handling non-MapReduce job and vacating resources as soon as possible is very desirable for our high throughput community.
Please let me know If you think this is already possible in Hadoop. Otherwise, we would be happy to work on contributing a patch to be included in Hadoop to server this purpose. Thanks for your help. -- Faisal Condor Project
