Mac spark-shell Error initializing SparkContext

Question

I tried to start spark 1.6.0 (spark-1.6.0-bin-hadoop2.4) on Mac OS Yosemite 10.10.5 using

\"./bin/spark-shell\". 

It has the error below.

Answer 1

In Mac,Check IP in System Preference -> Network -> click the Wifi you are connected(it should show green icon) -> check the IP just above your Network Name.

Make following entry in ../conf/spark-env.sh :

SPARK_MASTER_HOST=<>
SPARK_LOCAL_IP=<>

and than try spark-shell. Doing above changes worked for me.
