    Description

      HIVE-17526 (only on branch-1) disabled conversion to ACID if there are *_copy_N files under the table, but the filesystem checks introduced there are running for every insert since the MoveTask in the end of the insert will call alterTable eventually.

      The filename checking also recurses into staging directories created by other inserts. If those are removed while listing the files, it leads to the following exception and failing insert:

      java.io.FileNotFoundException: File hdfs://mycluster/apps/hive/warehouse/dvoros.db/concurrent_insert/.hive-staging_hive_2017-10-30_13-23-35_056_2844419018556002410-2/-ext-10001 does not exist.

      We should:

      • run checks only when converting to ACID and not on every alter (as we do on master)
      • skip hidden files to prevent recursing into staging directories
