Hari Sankar Sivarama Subramaniyan updated HIVE-5199:
----------------------------------------------------
Description:
The issue happens because of the changes in HIVE-3833.
Consider a partitioned table with different custom serdes for the partition and
tables. The serde at table level, say, customSerDe1's object inspector is of
settableDataType where as the serde at partition level, say, customSerDe2's
object inspector is of nonSettableDataType. The current implementation
introduced by HIVE-3833 does not convert nested Complex Data Types which extend
nonSettableObjectInspector to a settableObjectInspector type inside
ObjectInspectorConverters.getConvertedOI(). However, it tries to typecast the
nonSettableObjectInspector to a settableObjectInspector inside
ObjectInspectorConverters.getConverter(ObjectInspector inputOI, ObjectInspector
outputOI).
The attached patch HIVE-5199.2.patch.txt contains a stand-alone test case.
The below exception can happen via FetchOperator as well as MapOperator.
For example, consider the FetchOperator.
Inside FetchOperator consider the following call:
getRecordReader()->ObjectInspectorConverters. getConverter()
The stack trace as follows:

The below exception can happen via FetchOperator as well as MapOperator.
For example, consider the FetchOperator.
Inside FetchOperator consider the following call:
getRecordReader()->ObjectInspectorConverters. getConverter()
The output object inspector is of settable type(because it is generated via
ObjectInspectorConverters.getConvertedOI()) where as the input object inspector
that gets passed as serde.getObjectorInspector() and is non-settable. Inside
getConverter(), the (inputOI.equals(outputOI)) check fails and the switch
statement tries to cast the non-settable object inspector to a settable object
inspector.
