Frequently Asked Questions
  • When I enter spark parse some-file, I get the following error, what does it mean?

    "some-file" (line ..., column ...):
    unexpected end of input
    expecting Comment
    

    The first thing spark does when parsing a file, is removing all the comments. If your file is so badly formatted that even this goes wrong, you're probably trying to parse the wrong file.

  • When I try to use the variable HOST, spark cannot resolve it even though it is there when I enter echo $HOST.

    This means the variable HOST has not been exported. Bash does not do this automatically. You can export HOST manually with export HOST.
