Subject [jira] [Commented] (HBASE-15978) Netty API leaked into public API
Date Sat, 11 Jun 2016 14:17:20 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15978?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15325872#comment-15325872

Jurriaan Mous commented on HBASE-15978:

I also experimented with a version that is able to work with Guava ListenableFutures which
leaks nothing and adds a addListener(Runnable, Executor). It has the advantage of choosing
on which Executor to run the Runnable. But without leaking it cannot use the utilities of
Guava to add Callbacks. I would prefer to choose a standard implementation and be able to
built upon that. Are we able to leak implementations? Or do we need to build our own ListenableFuture
infrastructure? (See Futures class of Guava)

interface extends Netty, which means our public API is bound to a specific Netty API and release.
IIRC we were minimizing our public-facing surface area and asserting ownership over the whole
of it so as to control our compatibility. Ie, we've done this with Protobuf as well. Not sure
if this has made it back to other branches.
