> ExportSnapshot need to copy snapshot manifest to destination cluster first, 
> then setOwner and setPermission for those paths. But it's done with one 
> thread, which lead to a long time to submit the job if your snapshot is big. 
> I tried to make them processing in parallel, which can reduce the total time 
> of submitting dramatically.
