Why does Spark not run locally while it should be possible according the documentation? - apache-spark

Question

The aim is to get started with Spark by executing some examples and investigate the output.
I have cloned the Apache Spark repository, built it following the instructions in the Readme and ran ./bin/spark-shell that results in:
Using Spark's default log4j profile: org/apache/spark/log4j-defaults.properties
Setting default log level to "WARN".
To adjust logging level use sc.setLogLevel(newLevel). For SparkR, use setLogLevel(newLevel).

Answer 1

Try the following two directions:
1) Help spark find your IP:
if your hostname isn't included in /etc/hosts add it to /etc/hosts
127.0.0.1 your_hostname
set environment variable SPARK_LOCAL_IP="127.0.0.1"
2) if exists - kill old spark process

Answer 2

You need to set environment variable SPARK_LOCAL_IP="127.0.0.1",
or run,
export SPARK_LOCAL_IP="127.0.0.1"
If this doesn't solve your problem, run command hostname on terminal, make sure this hostname exists in your \etc\hosts file.

Answer 3

This solution is not for someone running on cluster machine of their own but on clouderaVM. While working on clouderaVM, I was getting the same error and the above solution didn't work.
Cause when i did
cat /etc/hosts/
192.168.245.*** quickstart.cloudera
This id is different than my actual ip which my VM was running on. you can check that using ifconfig.
Solution is to shutdown the VM and restart it.
