Subject [jira] [Commented] (HBASE-9633) Partial reverse of HBASE-9533
Date Mon, 23 Sep 2013 16:00:05 GMT

    [ https://issues.apache.org/jira/browse/HBASE-9633?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13774663#comment-13774663

Nicolas Liochon commented on HBASE-9633:

It (seems to) works because we have the dependency through zookeeper. But it's a little bit
dangerous, because we're downgrading a third party (i.e. core hadoop is tested with 3.6x and
we're running it with 3.2). And it's not nice for our end users :-).

> In netty 3.3, they changed the group id, if I understand well for legal reasons see https://github.com/netty/netty/issues/103).
But they have not changed the java package name: it's still org.jboss.netty. So we should
not have to remove our dependency to netty 3.6. 
> So:
> - this comment is wrong imho: the explicit load is not related to the package name but
to how mapreduce load work.
> {code}
> +      // This is ugly.  Our zk3.4.5 depends on the org.jboss.netty, not hadoops io.netty
> +      // so need to load it up explicitly while on 3.4.5 zk
> {code}
> - We do use Netty (for the multicast message), so now we're have a missing dependency,
as maven says:
> {code}
>  [INFO] — maven-dependency-plugin:2.1:analyze (default-cli) @ hbase-client —
> [WARNING] Used undeclared dependencies found:
> [WARNING] org.jboss.netty:netty:jar:3.2.2.Final:compile
> {code}
> So I propose a partial reverse. [~saint.ack@gmail.com], [@Aleksandr Shulman] would it
work for you?
