I'm a newbie of spark, and curently stryggling to run first spark-submit job. I initially configured spark on yarn on 4 node cloudera cluster, but if i do so, i could not see master and worker roles. Furthermore i cannot see any instances of spark except History server in cloudera manager UI. And i'm not sure what to pass for --master argument while doing spark-submit. If i do yarn-cluster nothing happend and job dies automatically, but if i do spark://master-node:7077 there is some error about cannot finding workers. I have to do start-all.sh manually, and even if i do so, it canot find workers. What actually am i doing wrong here? Is is spark-configuratioon issue with spark on yarn or something else?
