-------------------------------------
Summary: ThriftSchemaConverter throws for unknown struct or union
type
Key: PARQUET-346
URL: https://issues.apache.org/jira/browse/PARQUET-346
Project: Parquet
Issue Type: Bug
Components: parquet-mr
Reporter: Alex Levenson
ThriftSchemaConverter should either only be called on ThriftStruct's that have
populated structOrUnionType metadata, or should support a mode where this data
is unknown w/o throwing an exception.
Currently it is called using the file's metadata here:
https://github.com/apache/parquet-mr/blob/d6f082b9be5d507ff60c6bc83a179cc44015ab97/parquet-thrift/src/main/java/org/apache/parquet/thrift/ThriftRecordConverter.java#L797
One workaround is not not use the file matadata here but rather the schema from
the thrift class. The other is to support unknown struct or union types
