why is it binding to port 0? :/

Check the ip address of that master machine (ifconfig) looks like the ip address has been changed (hoping you are running this machines on a LAN)

I saw the same error reported before and have tried the following solutions.

Set the variable SPARK_LOCAL_IP ,Changed the SPARK_MASTER_PORT to a different number..But nothing is working.

When I try to start the worker from the respective machines using the following java command,its running without any exception

java -cp ::/usr/local/spark-1.0.0/conf:/usr/local/spark-1.0.0/assembly/target/scala-2.10/spark-assembly-1.0.0-hadoop1.2.1.jar -XX:MaxPermSize=128m -Dspark.akka.logLifecycleEvents=true -Xms512m -Xmx512m org.apache.spark.deploy.worker.Worker spark://:master:7077

Somebody please give a solution
Thanks & Regards,
