Subject Windows - Spark 2 - Standalone - Worker not able to connect to Master
Date Mon, 01 Aug 2016 01:24:50 GMT
Hi

I just downloaded Spark 2.0 on my windows 7 to check it out. However, not
able to set up a standalone cluster:


Step 1: master set up (Successful)

bin/spark-class org.apache.spark.deploy.master.Master

It did throw an error about not able to find winutils, but started
successfully.

Step II: Set up Worker (Failed)

bin/spark-class org.apache.spark.deploy.worker.Worker spark://localhost:7077

This step fails with following error:

16/08/01 11:21:27 INFO Worker: Connecting to master localhost:7077...
16/08/01 11:21:28 WARN Worker: Failed to connect to master localhost:7077
