spark-class: line 71...No such file or directory

I've installed Spark 2.1.1 on Ubuntu and no matter what I do, it doesn't seem to agree with the java path. When I run "spark-submit --version" or "spark-shell" I get the following error: /usr/local/spark/bin/spark-class: line 71: /usr/lib/jvm/java-8-openjdk-amd64/jre/bin//bin/java: No such file or directory Now obviously the "/bin//bin/java" is problematic, but I'm not sure where to change the configuration. The spark-class file has the following lines: ``` if [ -n "${JAVA_HOME}" ]; then RUNNER="${JAVA_HOME}/bin/java" ``` I was originally using a version of Spark meant for Hadoop 2.4 and when I changed it to "RUNNER="${JAVA_HOME}" it would either give me the error "[path] is a directory" or "[path] is not a directory." This was after also trying multiple path permutations in /etc/environment What I now have in /etc/environment is: JAVA_HOME="/usr/lib/jvm/java-8-openjdk-amd64/jre/bin/" This is the current java setup that I have: root@ubuntu:~# update-alternatives --config java There is only one alternative in link group java (providing /usr/bin/java): /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java bashrc has the following: ``` export SPARK_HOME="/usr/local/spark" export PATH="$PATH:$SPARK_HOME/bin" ``` Can anyone advise: 1) What files I need to change and 2) how I need to change them? Thanks in advance. spark-class file is in the link, just in case: http://vaughn-s.net/hadoop/spark-class
