> Rework CSV import to support very wide files
> --------------------------------------------
>
>                 Key: FLINK-2186
>                 URL: https://issues.apache.org/jira/browse/FLINK-2186
>             Project: Flink
>          Issue Type: Improvement
>          Components: Machine Learning Library, Scala API
>            Reporter: Theodore Vasiloudis
>
> In the current readVcsFile implementation, importing CSV files with many 
> columns can become from cumbersome to impossible.
> For example to import an 11 column file we need to write:
> {code}
> val cancer = env.readCsvFile[(String, String, String, String, String, String, 
> String, String, String, String, 
> String)]("/path/to/breast-cancer-wisconsin.data")
> {code}
> For many use cases in Machine Learning we might have CSV files with thousands 
> or millions of columns that we want to import as vectors.
> In that case using the current readCsvFile method becomes impossible.
> We therefore need to rework the current function, or create a new one that 
> will allow us to import CSV files with an arbitrary number of columns.
