Andrew Purtell commented on HBASE-12914:
----------------------------------------

No, this issue is about marking classes in 0.98 -- it's right there in the 
subject -- that are unstable because we said HFileV3 and all features depending 
on it are experimental for the lifetime of the release line. We should not be 
marking them unstable in 1.0, since HFileV3 is no longer declared experimental. 
It's a separate issue if you want to look at the features individually. I think 
a branch-1 patch with unstable tags is incorrect in the scope of this issue and 
with respect to the status of HFile v3 in 1.0 (if it's not stable, why is it 
the default??)

> There are several features in 0.98 that require enabling HFilev3 support. 
> Some of those features include new extendable components that are marked 
> IA.Public.
> Current practice has been to treat these features as experimental. This has 
> included pushing non-compatible changes to branch-1 as the API got worked out 
> through use in 0.98.
> * Update all of the IA.Public classes involved to make sure they are 
> IS.Unstable in 0.98.
> * Update the ref guide section on upgrading from 0.98 -> 1.0 to make folks 
> aware of these changes.
