Hi all, I'm a newcomer to Hadoop development, and I'm planning to work on an idea that I wanted to run by the dev community.
My apologies if this is not the right place to post this. Amazon has an "Elastic MapReduce" Service ( http://aws.amazon.com/elasticmapreduce/) that runs on Hadoop. The service allows dynamic/runtime changes in resource allocation: more specifically, varying the number of compute nodes that a job is running on. I was wondering if such a facility could be added to the publicly available Hadoop MapReduce. Does this idea make sense, has any previous work been done on this? I'd appreciate it if someone could point me the right way to find out more! Thanks a lot in advance! -- Bharath Ravi
