Summary: Write up how InterfaceAudience works over class hierarchy
Key: HBASE-19254
URL: https://issues.apache.org/jira/browse/HBASE-19254
Project: HBase
Issue Type: Task
Components: documentation
Reporter: stack
Over on the tail of HBASE-19235, there is a discussion around marking classes
with InterfaceAudicence in a hierarchy. One camp suggests that it could be
possible that a super class might be IA.Private but subclasses (and their
methods) could then be IA.LP. General opinion held the opposite. [~chia7712]
said it best:
bq. It makes sense to me that sub-class can always narrow the declaration (ex.
IA.Public -> IA.Private/IA.LP). Widening the declaration is like a issue we
need to fix.....
This issue is about adding a note to the IA section in refguide (should
probably pass it by dev list before it goes into refguide).
