I just installed spark on my new machine and get the following error after installing Java, Scala and Apache-spark using homebrew. The install process is given below:
$ brew cask install java
$ brew install scala
$ brew install apache-spark
Once installed, when I try to run a basic example using spark-shell
, i get the following error. Any help greatly appreciated.
$ spark-shell
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).
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.

Spark is incompatible with Java 9, which is the version brew cask install java
will install if it is up to date. If you did install Java 9, what you need to do is install Java 8 instead:
brew cask uninstall java
brew tap caskroom/versions
brew cask search java
brew cask install java8
As ZackK wrote spark is incompatible with Java9, so you can check the versions of java you have in your machine and choose a compatible version, assuming you have one.
$ sudo update-alternatives --config java
Which in my case returned:
There are 2 choices for the alternative java (providing /usr/bin/java).
The asterisk in front of 1 denotes the active version. Choosing 0 changed it to a compatible version.
$ java -version
which returned: openjdk version "1.8.0_151"
After the change spark-shell worked.
I faced same problem. But when I checked my laptop java version, it was 9. I just changed to java 8 and found every thing working fine.
Just check this solution. Hope it will work if you getting exact same error as start of this thread.
