I've tried to import tsv data by using importtsv tools. But the task failed
with the following errors.

If the line contains invalid data, the parser should throw BadTsvLineException.
But unfortunately, the codepath throws IllegalArgumentException for the empty
line, and that wasn't caught in the map() function.
