anyway.

webhdfs. We can't use the excuse of mustn't break downstream app classpath

Thinking ahead

2014-04-12 Thread Arun C Murthy
Gang, 

 With hadoop-2.4 out, it's time to think ahead.

 In the short-term hadoop-2.4.1 is in order; particularly with 
https://issues.apache.org/jira/browse/MAPREDUCE-5830 (it's a break to @Private 
API, unfortunately something Hive is using - sigh!). There are some other fixes 
which testing has uncovered; so it will be nice to pull them them in. I'm 
thinking of an RC by end of the coming week - committers, please be *very* 
conservative when getting stuff into 2.4.1 (i.e. merging to branch-2.4).

 Next up, hadoop-2.5.

 I've updated https://wiki.apache.org/hadoop/Roadmap with some candidates for 
consideration - please chime in and say 'aye'/'nay' or add new content. IAC, I 
suspect that list is too large.

 Rather than wait for everything it would be better to plan on releasing it on 
a time-bound manner; particularly around the Hadoop Summit. If that makes 
sense; I think we should target branching for 2.5 by mid-May to get it stable 
and released by early June.

 Thoughts?

thanks,
Arun

i disagree, mustn't break downstream app classpath is not an excuse, but a 
requirement. 

if you can make 2 versions of jetty to coexist because they are different 
packages (all their public apis) and they dont bump up transitive dependencies 
that break other things then is ok

Re: Thinking ahead

2014-04-12 Thread Sandy Ryza
+1 for starting to think about 2.5.  Early June seems a little early to me
- we had talked about a quarterly release cadence and this would be about
half that.

I'm having trouble editing the wiki, but I think Timeline Server stability
(e.g. security and locking down APIs) should go on that list.  I think we
should probably take YARN-1404 off the list - even with 3 months it's
unlikely to be complete.

 The proposed content for 2.5 in the roadmap wiki looks good to me.

   Thoughts?

Re: Thinking ahead

+1 for Timeline Server stability. In addition to the security, we may also
want to deal with scalability, generic and per-framework services
integration and MR integration.

Any plan about YARN long running services?

 +1 for starting to think about 2.5.  Early June seems a little early to me
 - we had talked about a quarterly release cadence and this would be about
 half that.

 I'm having trouble editing the wiki, but I think Timeline Server stability
 (e.g. security and locking down APIs) should go on that list.  I think we
 should probably take YARN-1404 off the list - even with 3 months it's
 unlikely to be complete.
