[jira] Commented: (HADOOP-6676) Create a javac plugin that produces
warnings for programs using Evolving APIs
[ https://issues.apache.org/jira/browse/HADOOP-6676?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12854224#action_12854224 ]
Tom White commented on HADOOP-6676:
-----------------------------------
I'm not sure we can use an annotation processor for this, since (by my reading) they process annotations that appear in the source being compiled, rather than annotations that are _referenced_ by the source being compiled.
Anyone got any suggestions for how this might be implemented?

> Such a feature would be useful to enforce MAPREDUCE-1637. It might also be useful for users who wish to check their programs don't use Evolving APIs.
> It could be implemented using an annotation processor: http://java.sun.com/javase/6/docs/technotes/tools/solaris/javac.html#processing
