> Key: HIVE-5285
> URL: https://issues.apache.org/jira/browse/HIVE-5285
> Project: Hive
> Issue Type: Bug
> Affects Versions: 0.11.1
> Reporter: Hari Sankar Sivarama Subramaniyan
> Assignee: Hari Sankar Sivarama Subramaniyan
> Priority: Critical
> Fix For: 0.13.0
>
> Attachments: HIVE-5285.1.patch.txt, HIVE-5285.2.patch.txt
>
>
> The approach for HIVE-5199 fix is correct.However, the fix for HIVE-5199 is
> incomplete. Consider a complex nested structure containing the following
> object inspector hierarchy:
> SettableStructObjectInspector
> {
> ListObjectInspector<NonSettableStructObjectInspector>
> }
> In the above case, the cast exception can happen via
> MapOperator/FetchOperator as below:
> java.io.IOException: java.lang.ClassCastException:
> com.skype.data.hadoop.hive.proto.CustomObjectInspector cannot be cast to
> org.apache.hadoop.hive.serde2.objectinspector.SettableMapObjectInspector
