----------------------------------------
Summary: Support casting integer types to BinaryType
Key: SPARK-27174
URL: https://issues.apache.org/jira/browse/SPARK-27174
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 3.0.0
Reporter: Martin Junghanns
Currently, only {{StringType}} can be cast to {{BinaryType}}.
Integer types also have a well known two's complement binary representation and
can therefore be unambiguously cast to {{BinaryType}}.
This PR adds support for casting
* {{ByteType}}
* {{ShortType}}
* {{IntegerType}}
* {{LongType}}
to {{BinaryType}}.
