Re: Given a Put object, is there any way to change the timestamp of it?

Put is marked @InterfaceStability.Stable though Mutation is marked with @
InterfaceStability.Evolving

I doubt setTimeStamp() would be added.

 Thanks Ted!
 This is exactly what I need.

 This will be a memory copy, but it solves my problem. Hope HBase can
 provide a setTimeStamp() method in future release.

 bq. I have no way to get ALL its cells out Mutation has the following
 method:

   public NavigableMapbyte [], ListCell getFamilyCellMap() {
