      Description

      Consider a metastore Parquet table that

      1. doesn't have schema evolution issue
      2. has lots of data files and/or partitions

      In this case, driver schema merging can be both slow and unnecessary. Would be good to have a configuration to let the use disable schema merging when converting such a metastore Parquet table.
