That would remain a workaround though. The uniVocity parser for boolean
supports this as well:
https://github.com/uniVocity/univocity-parsers/blob/master/src/main/java/com/univocity/parsers/conversions/BooleanConversion.java.
It's also been raised as a ticket against the original spark-csv so there
seems to be at least some interest. Personally, I think this can help a lot
when integrating Spark with other systems (i.e. some DB exports where modeling
booleans as flags is common) similar to having ways of specifying the format of
a date or null value.
