Hi, I did netstat -na | grep 192.168.125.174 and its showing 192.168.125.174:7077 LISTEN(after starting master)
I tried to execute the following script from the slaves manually but it ends up with the same exception and log.This script is internally executing the java command. /usr/local/spark-1.0.0/sbin/start-slave.sh 1 spark://192.168.125.174:7077 In this case netstat is showing any connection established to master:7077. When we manually execute the java command,the connection is getting established to master.
