Can't work with spark

[nonlinearthink]

I'm a beginner in Data Science.

Before that, I used jenv to manage multiple Java versions, but when I used spark, I found that spark couldn't run.

CLI reports an error as follows:

/usr/local/spark/bin/spark-class: line 99: /Users/jayceechow/.jenv/versions/system/bin/java: No such file or directory
/usr/local/spark/bin/spark-class: line 99: exec: /Users/jayceechow/.jenv/versions/system/bin/java: cannot execute: No such file or directory

I guess this may be caused by jenv, so I uninstalled jenv and deleted the related content of .zshrc, and now spark is running well.

I think jenv is great. I hope it can be solved.

This is a problem when using system as the version for java. In that case the export plugin erroneously sets JAVA_HOME to $JENV_ROOT/versions/system which does not exist.

#422 should resolve this - once merge in you would then be able to set JAVA_HOME for spark to pick up. e.g.

jenv shell 17
# do some stuff
jenv shell system
export JAVA_HOME=/path/to/java/home
spark ...

Alternatively setting an explicit version should work correctly e.g.

jenv shell 11
spark ...
