Are there circumstances where an Akka-based application can replace a Hadoop setup? -
from reading akka , own beginning uses of it, seems me akka used, , more simply, hadoop setup applications. wouldn't have hdfs use, write application send out pieces of work different "mappers" , have results sent "reducer", , easier set hadoop in vms or on hardware, fewer services set up. reasonable or 2 technologies used totally different things?
yes, totally reasonable. have built large scale (1000+ workers) map-reduce system using akka 2.0. akka 2.2+ better because can use clustering , remote deathwatch features instead of having write functionality yourself.
see this post feel how might work.
