Evan McClain created PARQUET-856:
------------------------------------
Summary: parquet-avro logical type support broke ability to use
avro reflection with generics.
Key: PARQUET-856
URL: https://issues.apache.org/jira/browse/PARQUET-856
Project: Parquet
Issue Type: Bug
Components: parquet-avro
Affects Versions: 1.9.0
Reporter: Evan McClain
Priority: Minor
Impacts 1.9.0 and 1.8.2.
Assuming the fieldClass is a concrete class (which it is for all of the logical
types) is an incorrect assumption when generics are used.
Statistics<T extends Serializable> {
T field1
T field2
}
SetStatistics extends Statistics<HashSet<String>> {}
Solution is to check if the fieldClass is abstract/interface/raw object.
