> Currently the criteria of whether a merge job should be fired on dynamic
> generated partitions are is the average file size of files across all dynamic
> partitions. It is very common that some dynamic partitions contains mostly
> large files and some contains mostly small files. Even though the average
> size of the total files are larger than the hive.merge.smallfiles.avgsize, we
> should merge those partitions containing small files only.
