-----------------------------------------
Summary: StructType.fromString swallows exceptions from
DataType.fromJson
Key: SPARK-23696
URL: https://issues.apache.org/jira/browse/SPARK-23696
Project: Spark
Issue Type: Bug
Components: ML
Affects Versions: 2.2.1
Reporter: Simeon H.K. Fitch
`StructType.fromString` swallows exceptions from `DataType.fromJson`, assuming
they are an indication that the `LegacyTypeStringParser.parse` should be called
instead. When that fails (because it throws an excreption), an error message is
generated that does not reflect the true problem at hand, effectively
swallowing the exception from `DataType.fromJson`. This makes debugging Parquet
schema issues more difficult.
