问题 I'm trying to run a Scala Spark job that uses the Univocity CSV Parser and after upgrading to support a String delimiter (vs only character), I'm getting the following error when I run my jar in the cluster. Running it locally in my IDEA IDE produces expected results with no errors.

问题 I'm trying to read CSV files from GTFS.zip with help of uniVocity-parsers and run into an issue that I can't figure out. For some reason it seems the first column of some CSV files won't be parsed correctly.
