--------------------------------------
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
