Lars Hofhansl commented on HBASE-5923:
--------------------------------------

Thanks Stack. These are exactly the concerns I had.

It becomes even more pronounced when looking at the 0.94 patch, which needs to 
have a slightly different client facing API - since the PB stuff not exist 
there.

I can see a few solutions:
* Only allow using WritableByteArrayComparable, i.e. make it implied and don't 
even pass it (and hence only create the dependency for HTable but not 
HTableInterface).
* As you said, have a separate CompareOp class that gets translated to the 
correct compareType in HTable (again would allow only HTable having the 
dependency, but not HTableInterface)

> 1. the checkAnd{Put|Delete} method that takes a CompareOP is not exposed via 
> HTable[Interface].
> 2. there is unnecessary duplicate code in the check{Put|Delete} code in 
> HRegionServer.
