   > you use deprecated function, I am not sure if SparkActions also has this 
problem, I will research the generation strategy of the manifest later.
   
   I think this is no problem. I think that rewriting files generate a 
snapshot, contain add and delete for a operation. If you want remove older data 
file , you need to generate a new snapshot exclude delete references, like 
rewritemanifest? I am not sure if the understanding of snapshots and operations 
is correct
