Subject Re: WTF: Difference between schemas across branches?
Date Tue, 02 Dec 2014 11:47:12 GMT
Thanks for replying Nitin. I've picked the latest fix, both schema files
are semantically same now.

If we're fixing/back-porting bug-fixes to all branches where a bug
exists and making sure we're not introducing differences in schema, by
doing that in a way we're helping the overall community (and not just
coding) and living the Apache way of community over code.

I think if our day-job allow us to fix then it should *ideally* allow us
to fix a bug on all the affected branches. I noticed recently within the
community that a lot of companies who may provide such ideal
environments are looking for good developers.

Some folks expressed concerns over the email subject. They were all
right, the subject contains a typo that I forgot to remove.
