Re: LimitedPrivate and HBase (thoughts from an observer)
I do not see any issue with the change that Todd has made. We have done
similar changes in HDFS-1586 in the past.

Making APIs public comes with a cost. That is what we are avoiding with
LimitedPrivate. The intention was to include the following projects that are
closely tied to Hadoop as projects eligible for LimitedPrivate.
{"HBase", "HDFS", "Hive", "MapReduce", "Pig"}. This list could grow in the

When such projects break because of API change, we can co-ordinate as
community and fix the issues. This is not true for some application that we
do not know of breaks!

If others, outside the umbrella of these projects need an API, they could
open a jira and we could address it.
