Aihua Xu updated HIVE-11696:
----------------------------
Attachment: HIVE-11696.2.patch
Since we are creating the object as a "ArrayList" in ParquetHiveArrayInspector,
seems not necessary to handle ArrayWritable, but should at least handle
ArrayList.
> Exception when table-level serde is Parquet while partition-level serde is
> JSON

> Create a table with partitions and set the SerDe to be Json. The query
> "select * from tbl1" works fine.
> Now set table level SerDe to be Parquet serde. Based on HIVE-6785, table
> level and partition level can have different serdes.
