I am trying to setup a spark standalone cluster with 3 nodes. Configurations for Linux servers are below:
master node with 2 core and 25GB memory
worker node 1 with 4 core and 21GB memory
worker node 2 with 8 core and 19GB memory
I have started the master node successfully and its url is spark://IP:7077
when I start any of the worker node with command ./sbin/start-worker.sh spark://IP:7077 I get the below error message:
22/11/25 09:13:58 INFO Worker: Connecting to master IP:7077...
22/11/25 09:14:54 ERROR RpcOutboxMessage: Ask terminated before connecting successfully
22/11/25 09:14:54 WARN NettyRpcEnv: Ignored failure: java.io.IOException: Connecting to /IP:7077 timed out (120000 ms)
22/11/25 09:14:54 WARN Worker: Failed to connect to master IP:7077
org.apache.spark.SparkException: Exception thrown in awaitResult:
openjdk 11.0.17 is the java version installed on all the 3 nodes
Any solutions to resolve this issue will be helpful.
