Summary: Report conflicting fields when merging two StructTypes.
Key: SPARK-18950
URL: https://issues.apache.org/jira/browse/SPARK-18950
Project: Spark
Issue Type: Bug
Components: SQL
Reporter: Cheng Lian
Priority: Minor
Currently, {{StructType.merge()}} only reports data types of conflicting fields
when merging two incompatible schemas. It would be nice to also report the
field names for easier debugging.
