   Hey @dongjoon-hyun -- sure  API backward compatibility is definitely something we should keep an eye on -- I was personally trying to upgrade to 1.6 on HIVErecently and bumped into too many API incompatibilities.
   However, we could also use schema/schemaEvolution and SARGS to derive columnNames ( so we could maintain a deprecated getColumnNames() method without keeping the extra field in the Reader.Options).
   Would something like the above make sense?
