Github user fpompermaier commented on the issue:
https://github.com/apache/flink/pull/2297
For our use cases it is important to know whether a value of cell is empty
or it is 0.
The EMPTY_STRING error could be intercepted by the csv parser in order to
generate Row objects with null values instead of 0 using the Table API
> FieldParsers should support empty strings

> In order to parse CSV files using the new Table API that converts rows to Row
