> Distributed log replay is an awesome feature, but due of HBASE-11094, the rolling upgrade
story from 0.98 is hard to explain / enforce. 
> The fix for HBASE-11094 only went into 0.98.4, meaning rolling upgrades from 0.98.4-
might lose data during the upgrade. 
> I feel no matter how much documentation / warning we do, we cannot prevent users from
doing rolling upgrades from 0.98.4- to 1.0. And we do not want to inconvenience the user by
requiring a two step rolling upgrade.  
> Thus I think we should disable dist log replay for 1.0, and re-enable it again for 1.1
(if rolling upgrade from 0.98 is not supported). 
> ie. undo: HBASE-10888
