------------------------------------
Summary: OptionTypeInfo does not have proper equals and hashCode
method
Key: FLINK-2633
URL: https://issues.apache.org/jira/browse/FLINK-2633
Project: Flink
Issue Type: Bug
Reporter: Till Rohrmann
The {{OptionTypeInfo}} does not have a proper {{equals}} and {{hashCode}}
definition. As a consequence, types which contain an option type won't be
detected to be equal even though the element type of the option is identical.
This can cause problems when you try to union two data sets of type
{{DataSet[Option[Int]]}}, for example.
