    Description

      As discussed in HIVE-16177, non-ACID to ACID conversion can lead to data loss if the table has *_copy_N files.

      The patch for HIVE-16177 is quite massive and would basically need a reimplementation to apply for branch-1 since the related code paths have diverged a lot. We could disable the conversion to ACID if there are *_copy_N files instead.
