Patch #3 failure TestCliDriver parquet_no_row_serde is related.  New semantics that vector
row deserialization of input formats that support vectorized input format no longer supported.

 

Same with TestSparkCliDriver vectorization_input_format_excludes.

> LLAP is able to deserialize and cache data from an input format (e.g. TextInputFormat)
and will deliver that cached data to VectorMapOperator as VRBs.
> Symptoms:
>    BinaryComparable -> VectorizedRowBatch ClassCastException
>    Text -> VectorizedRowBatch ClassCastException
