Lars Hofhansl commented on HBASE-10262:
---------------------------------------

Please see (long'ish) discussion on HBASE-5923. If we allow control of the 
compareOp we need to allow for different comparators as well (for LESS, etc)
Or we can punt on that and just force binary comparator as we do not for EQUAL

> provide user/client checkAndPut/checkAndDelete API with full CompareOp rather 
> than only CompareOp.EQUAL

> currently checkAndPut/checkAndDelete provided by HTable doesn't support full 
> CompareOp other than CompareOp.EQUAL, which limits user/client from doing 
> more flexible checkAndPut/checkAndDelete operation. this improvement fixes 
> this limit by exposing additional checkAndPut/checkAndDelete API with full 
> CompareOp support.
