I am trying to install spark in a new Macbook. I couldn't run the spark-shell and get the following error:

Failed to initialize compiler: object java.lang.Object in compiler mirror not     found.
** Note that as of 2.8 scala does not assume use of the java classpath.
** For the old behavior pass -usejavacp to scala, or if using a Settings
** object programmatically, settings.usejavacp.value = true.

Exception in thread "main" java.lang.NullPointerException

First, install Java 8 (You can keep Java 9 if that's what you have).

Then, in your .bash_profile, set JAVA_HOME as follows:

export JAVA_HOME=$(/usr/libexec/java_home -v 1.8)  
export PATH=$JAVA_HOME/bin:$PATH

Finally, add this: 

export SPARK_LOCAL_IP="127.0.0.1"

Hope this helps. There is a nice trick on how to alternate between different Java versions here:
Mac OS X and multiple Java versions Check out the answer by @Vegard.

This is my setting: 

export JAVA_HOME=$(/usr/libexec/java_home -v 1.8)  
export PATH=$JAVA_HOME/bin:$PATH

export SCALA_HOME=/path/to/your/scala  
export PATH=$PATH:$SCALA_HOME/bin

export SPARK_HOME=/path/to/your/spark  
export PATH="$SPARK_HOME/bin:$PATH"  
export SPARK_LOCAL_IP="127.0.0.1"

I get the same error when trying to run spark-shell with Java 9.

Please try installing Java 8 and running spark-shell with JAVA_HOME set to /Library/Java/JavaVirtualMachines/jdk1.8.0.jdk/Contents/Home

For more information about JDK 9 support in Scala you can look a scala-dev issue #139

In my case it was brew command who changed JAVA_HOME just for spark-submit and other spark-related command.

Check with brew info apache-spark - see content of the formula. In mine there was fixed javasdk@11.

So I had to edit this ruby file to use current $JAVA_HOME. And brew reinstall apache-spark. After that the error gone and the spark-commands use the java version that I have chosen at the moment with jenv
