             Summary: Fixing shifting index issue related to object inspector caching
                 Key: HIVE-15130
                 URL: https://issues.apache.org/jira/browse/HIVE-15130
             Project: Hive
          Issue Type: Sub-task
          Components: Reader
            Reporter: Chao Sun
            Assignee: Chao Sun


Hive caches object inspector in memory to avoid recreating the same object.
However, in {{ArrayWritableObjectInspector}}, the {{equals}} and {{hashCode}} doesn't take account on all attributes of the class, therefore, even though the internal state (e.g., {{adjustedIndex}}) is different, it could still be mapped to the same result. This could cause wrong field index being used when reading Parquet data.
