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. I also tried to install different versions of Spark but all have the same error. This is the second time I'm running Spark. My previous run works fine.

Then I add

export SPARK_LOCAL_IP="127.0.0.1" 

to spark-env.sh, error changes to:

 ERROR : No route to host     java.net.ConnectException: No route to host         at java.net.Inet6AddressImpl.isReachable0(Native Method)         at java.net.Inet6AddressImpl.isReachable(Inet6AddressImpl.java:77)         at java.net.InetAddress.isReachable(InetAddress.java:475) ... <console>:10: error: not found: value sqlContext        import sqlContext.implicits._               ^ <console>:10: error: not found: value sqlContext        import sqlContext.sql 

Answer 1

Following steps might help:

1. Get your hostname by using "hostname" command.

2. Make an entry in the /etc/hosts file for your hostname if not present as follows:

   127.0.0.1      your_hostname 

Hope this helps!!
