> The exception is because the serialization and deserialization doesn't match.
> The serialization by LazyBinarySerDe from previous MapReduce job used
> different order of columns. When the current MapReduce job deserialized the
> intermediate sequence file generated by previous MapReduce job, it will get
> corrupted data from the deserialization using wrong order of columns by
> LazyBinaryStruct. The unmatched columns between serialization and
> deserialization is caused by SelectOperator's Column Pruning
> {{ColumnPrunerSelectProc}}.
