Subject [jira] [Commented] (HADOOP-9151) Include RPC error info in RpcResponseHeader instead of sending it separately
Date Sat, 22 Dec 2012 11:17:12 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-9151?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13538753#comment-13538753

Arun C Murthy commented on HADOOP-9151:

Thanks, I appreciate you being upfront - but it doesn't change the merits of your veto. As
others have pointed out, you are welcome to continue shipping CDH without these changes.

The 'alpha'/'beta' tags are meant to be a warning to end-users about the stability of the
software (apis, wire-protocols etc.) and users can make their own decisions. We've discussed
this many times for very good reasons - for e.g. the PB-based HDFS protocols are very raw
(~12 months old at this point v/s Writables' RPC viz. nearly 4-5yrs now) and it's not surprising
we hit these issues, there may be further down the road.

Also, it isn't true that the discussion was limited to YARN, see the link I posted above w.r.t
HDFS from Suresh:  http://s.apache.org/qQp. I'm pretty sure you've ascribed to above views
too (w.r.t changing wire-protocols on HDFS etc.) - here is your own view that HDFS protocols
aren't 'baked' yet: http://s.apache.org/PRh

Having said that, I agree we maybe overblowing the current issue.

However, we might have to do more changes of this nature in the future (maybe major bugs or
new features etc. before hadoop-2 hits 'stable') and I really hope you won't be vetoing further
development on grounds of 'CDH compatibility'.
