Question

Answer 1

All solutions above didn't work for me, but I found one more way to fix problem: Stackoverflow: spark worker not connecting to master

Please check configuration file "spark-env.sh" on your master node. Have you set the SPARK_MASTER_HOST variable to the IP address of the master node? If not try to set it and restart the master and slaves. For example, if your master node's IP is 192.168.0.1, you should have SPARK_MASTER_HOST=192.168.0.1 in there. Note that you don't need to set this variable on your slaves.
