It's impossible to parse CSV file with more than 512 columns
See original GitHub issueI try to parse feature index file into Table (it’s about 2000x36000 matrix).
I try to use:
Table t = Table.read().csv(csv);
but got error from com.univocity.parsers.csv.CsvParser (log is attached 512-ERROR.txt) that there is more than 512 columns.
I’ve checked sources and found out that you create CsvParser with default settings, and there is no option to change some how this settings from your API.
I think there should be some way to change com.univocity.parsers.csv.CsvParserSettings from Table.read() place, or at least change columns size limit.
