      Description

      AbstractParquetMapInspector uses wrong class cast https://github.com/apache/hive/blob/trunk/ql/src/java/org/apache/hadoop/hive/ql/io/parquet/serde/AbstractParquetMapInspector.java#L144

      It should be AbstractParquetMapInspector

      final StandardParquetHiveMapInspector other = (StandardParquetHiveMapInspector) obj;
      

      Such conversion leads to class cast exception in case of DeepParquetHiveMapInspector.

      Caused by: 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
