> 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.
