Nick Dimiduk commented on HBASE-12889:
--------------------------------------

Our command line tools are a little schizophrenic. Have a look at 
TableInputFormat: all of these things are configurable IF no scan object is 
provided. IMHO, it would be better if we could expose this basic functionality 
across the board. I opened a ticket a while back to clean all this up, 
HBASE-8074. That's my preference over adding up a bunch of option flags on each 
tool, one by one.

> Add scanner caching and batching options for the CopyTable job.

> We use the copy table job to ship data between clusters.  Sometimes we have 
> very wide rows and it is nice to be able to set the batching and caching.  
> I'll attach trivial patches for you guys.
