Subject Re: [VOTE] Release Apache Hadoop 2.4.0
Date Mon, 07 Apr 2014 15:16:32 GMT
Gera,

 Apologies for the late response, I decided to take the weekend off! *smile*

 Thanks for the feedback, I took a look at your list and here are some observations:

 This is certainly unfortunate, but essentially it's just a bad default config value. As such,
there is a pretty simple & clear workaround which I'll release-doc.

 I had already commented on the jira around the time of RC as you may remember. Also, this
isn't a regression - this bug has existed for quite a while now. Furthermore, there are some
back-compatibility concerns we still need to address.

 Please accept my personal apologies, this wasn't on my radar to review. In future, pls drop
me a note if you don't see any activity on a jira you care about - I'm sure others like Vinod,
Jason etc. would love to help too; it's just something that got missed by the community collectively.
Having said that, as you can imagine, new features cannot be a blocker to a release; this
sets up a dynamic where it's impossible to please everyone and we cannot ship any release…
as you may have seen it's been quite an effort for the last 3-4 weeks just to corral everyone
into fixing/reviewing/committing blocker bugs itself. *smile*

 Overall, please feel free to share your feedback, but the above list doesn't seem to have
a critically bad release blocker. 
 
 Also, I plan to follow up with a 2.4.1 in a couple of weeks; I'll make sure to include as
much as your list as possible - and future ones.

thanks,
Arun
