             Summary: select * fails on parquet table with map datatype
                 Key: HIVE-6575
                 URL: https://issues.apache.org/jira/browse/HIVE-6575
             Project: Hive
          Issue Type: Bug
          Components: Serializers/Deserializers
    Affects Versions: 0.13.0
            Reporter: Szehon Ho
            Assignee: Szehon Ho


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.
