             Summary: ClassCastException in AbstractParquetMapInspector
                 Key: HIVE-6491
                 URL: https://issues.apache.org/jira/browse/HIVE-6491
             Project: Hive
          Issue Type: Bug
          Components: File Formats
         Environment: cdh5-beta2, trunk
            Reporter: Andrey Stepachev


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
{code:java}
final StandardParquetHiveMapInspector other = (StandardParquetHiveMapInspector) obj;
{code}

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

{code}
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
