> Create parquet table with map and run select * from parquet_table, returns
> following exception:
> {noformat}
> FAILED: RuntimeException java.lang.ClassCastException:
> org.apache.hadoop.hive.ql.io.parquet.serde.DeepParquetHiveMapInspector cannot
> be cast to
> org.apache.hadoop.hive.ql.io.parquet.serde.StandardParquetHiveMapInspector
> {noformat}
> However select <mapcol> from parquet_table seems to work, and thus joins will
> work.
