Spark could not bind on port 7077 with public IP

Question

I have installed spark on AWS. When I try to execute on AWS it works, but spark doesn't work, when I check the sparkMaster log I see the next:

Spark Command: /usr/lib/jvm/java-8-oracle/jre/bin/java -cp /home/ubuntu/spark/conf/:/home/ubuntu/spark/jars/* -Xmx1g org.apache.spark$

My /etc/hosts is the next:

127.0.0.1  localhost

    52.211.60.97    server1
    52.210.246.199  client1
    52.211.71.126   client2
    52.211.20.213   client3

    # The following lines are desirable for IPv6 capable hosts
    ::1     ip6-localhost ip6-loopback
    fe00::0 ip6-localnet
    ff00::0 ip6-mcastprefix
    ff02::1 ip6-allnodes
    ff02::2 ip6-allrouters

And this is my spark-env.sh:

export SPARK_WORKER_MEMORY=512m
export SPARK_EXECUTOR_MEMORY=512m
export SPARK_WORKER_INSTANCES=1
export SPARK_WORKER_CORES=1
export SPARK_WORKER_DIR=/home/ubuntu/spark
export SPARK_LOCAL_IP=52.211.60.97
export SPARK_MASTER_IP=52.211.60.97
export SPARK_MASTER_WEBUI_PORT=4041

I have try the same playbook, but using a AWS VPC with private instances and VPN and it works fine. So I think there is any problem with the public IP, maybe amazon block some ports on the public IP? or what could be the problem?

Answer 1

I was also facing similar issues. This is caused as the spark master is not able to open port on specified on SPARK_MASTER_IP. first, find your hostname by hostname command. After that, make sure your machine ip address in /etc/hosts is mapped to given hostname. After that, use that hostname for SPARK_MASTER_IP. For this issue, in cluster mode, you can also mention export SPARK_LOCAL_IP=127.0.0.1.
