Hello, there,

I am developing a coprocessor under HBase 0.98.6. The client send a Put object 
to the coprocessor in Protobuf, when the coprocessor receive the message , it 
invokes ProtobufUtil.toPut to convert it to a Put object. Do various checking  
and then put it into HBase table.
Now, I get a requirement to change the timestamp of that Put object, but I 
found no way to do this.

I was first try to generate a new Put object with a new timestamp, and try to 
copy the old one into this new object. But I found given a Put object, I have 
no way to get ALL its cells out if I don't know the column family and column 
qualifier name in advance. In my case, those CF/Column names are random as user 
defined. So I stuck here. Could anyone have idea how to workaround this?

The Mutation class has getTimestamp() method but no setTimestamp(). I wish 
there is a setTimestamp() for it. Is there any reason it is not provided? I 
hope in future release Mutation can expose a setTimestamp() method, is it 
possible? If so, my job will get much easier...

Thanks,
Ming
