> Observed:
> A couple of my client tests fail to compile against trunk because the method PerformanceEvaluation.generateValue
was removed as part of HBASE-8496.
> This is an issue because it was used in a number of places, including unit tests. Since
we did not explicitly label this API as private, it's ambiguous as to whether this could/should
have been used by people writing apps against 0.96. If they used it, then they would be broken
upon upgrade to 0.98 and trunk.
> Potential Solution:
> The method was renamed to generateData, but the logic is still the same. We can reintroduce
it as deprecated in 0.98, as compat shim over generateData. The patch should be a few lines.
We may also consider doing so in trunk, but I'd be just as fine with leaving it out.
> More generally, this raises the question about what other code is in this "grey-area",
where it is public, is used outside of the package, but is not explicitly labeled with an
AudienceInterface.
