I’m running a Hadoop cluster on AWS EC2,
I would like to dynamically resizing the cluster so as to reduce the cost, is there any solution to achieve this?
E.g. I would like to cut the cluster size with a half, is it safe to just shutdown the instances (if some tasks are just running on them, can I rely on the speculative execution to re-run them on other nodes?)
I cannot use EMR, since I’m running a customized version of Hadoop
