Fabian Hueske commented on FLINK-1872:
--------------------------------------
The names of the CSV fields are actually not important for Flink.
You need to know the data types of the fields, e.g., {{Integer, String, String}}
If you know the types, the
[documentation|http://ci.apache.org/projects/flink/flink-docs-master/programming_guide.html#data-sources]
should tell you how to read a CSV file.
> How can generation dataset in flink automatic depend on number of filed and
> data type
