   ```
   if (overwrite && !insertCommand.dynamicPartitionOverwrite) {
         DDLUtils.verifyNotReadPath(actualQuery, outputPath)
   }
   ```
   DynamicPartitionOverwrite does not delete data before job begin, so it will not encountered verify problem.
   
   Since we use directly outputCommitter to write files. For the case `Insert overwrite static partition from data read from same table's partition`, we just tune `insertCommand.dynamicPartitionOverwrite` to true to avoid delete partition data before read.
