I'm using Spark Standalone Mode tutorial page to install Spark in Standalone mode.
1- I have started a master by:
2- I have started a worker by:
./bin/spark-class org.apache.spark.deploy.worker.Worker spark://ubuntu:7077
spark://ubuntu:7077 is my master name, which I can see it in
Problem: By second command, a worker started successfully. But it couldn't associate with master. It tries repeatedly and then give this message:
15/02/08 11:30:04 WARN Remoting: Tried to associate with unreachable remote address [akka.tcp://sparkMaster@ubuntu:7077]. Address is now gated for 5000 ms, all messages to this address will be delivered to dead letters.

What is the problem?
