Nathan, I attempted to put the following line
worker.childopts: "-Xmx4096m -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:NewSize=128m -XX:CMSInitiatingOccupancyFraction=70 -XX: -CMSConcurrentMTEnabled Djava.net.preferIPv4Stack=true" in the supervisor config files, but for some reason workers were not spawned on those machines. To be more precise, I submitted my topology (with storm jar...) and I just waited for it to start executing, but nothing. Any ideas of what might have been the reason?
