Zhihong Yu commented on HBASE-5824:
-----------------------------------

In 0.94, client only needs to deal with RetriesExhaustedWithDetailsException whose only cause is a ConstraintException
With Jimmy's patch, client needs to deal with RetriesExhaustedWithDetailsException (not subclass of DoNotRetryIOException) and ConstraintException (subclass of DoNotRetryIOException). This is because there're two execution paths for Put.

I am afraid Benoit would have more to complain about in HBASE-5796 :-)

> on 0.94 a call to client.HTable#incrementColumnValue will cause HRegion#incrementColumnValue.  On trunk all calls to HTable.incrementColumnValue got to HRegion#increment.
> My guess is that HTable#incrementColumnValue and HTable#increment serialize to the same thing over the wire so that the remote HRegionServer no longer knows which htable method was called.
> To repro I checked out trunk and put a break point in HRegion#incrementColumnValue and then ran TestFromClientSide.  The breakpoint wasn't hit.
