Sebastian Kruse created FLINK-2229:
--------------------------------------
Summary: Data sets involving non-primitive arrays cannot be unioned
Key: FLINK-2229
URL: https://issues.apache.org/jira/browse/FLINK-2229
Project: Flink
Issue Type: Bug
Components: Java API
Affects Versions: 0.9
Reporter: Sebastian Kruse
The class {{ObjectArrayTypeInfo}} misses {{equals(...)}} and {{hashCode()}}.
This becomes an issue when applying a union to data sets that somehow involve
non-primitive arrays, because their data types appear to be different even
though they are not.
