> When the text scanner hits an error, it always prints the end of the file as the offset, even if the error occurs in the middle of the file. For example:
> {noformat}
> WARNINGS: Error converting column: 3 to INT
> Error parsing row: file: hdfs://localhost:20500/home/lv/sample_07/sample_07, before offset: 46055
> Error converting column: 3 to INT
> {noformat}
> We should instead print the offset of the problematic value to make debugging easier.
