Sergey Shelukhin updated HIVE-19793:
------------------------------------
Description:
1) Batch to row converter doesn't propagate columns correctly because they are
not in the schema.
2) Then, even if it did, the current VrbCtx model of ACID column propagation
only works with VectorMapOperator. Regular MapOperator has no such context; the
reader ends up storing the vector in some fake temporary ctx. I left a TODO
that combined with a fix to (1) could fix this instead of disabling it.
> disable LLAP IO batch-to-row wrapper for ACID deletes/updates
