Review comment:
       Can optimize as below:
   ```suggestion
        List<CarbonFile> carbonFiles;
       boolean recursive = false;
       if (table.isHivePartitionTable()) {
         path = table.getAbsoluteTableIdentifier().getTablePath();
         recursive = true;
       }
       carbonFiles = FileFactory.getCarbonFile(path).listFiles(recursive,
           file -> file.getName().endsWith(CarbonTablePath.INDEX_FILE_EXT) || file.getName()
               .endsWith(CarbonTablePath.MERGE_INDEX_FILE_EXT));
       CarbonFile[] validIndexFiles = (CarbonFile[]) SegmentFileStore
           .getValidCarbonIndexFiles(carbonFiles.toArray(new CarbonFile[carbonFiles.size()]));
   ```
