Subject Re: Thinking ahead to 2.4
Date Thu, 06 Mar 2014 21:40:54 GMT
Gang,

 Most of the big-ticket items are already in, awesome!

 I'm thinking we could roll out a 2.4 RC in the next 2-3 weeks after we get through the list
of blockers. Here is a handy link: http://s.apache.org/hadoop-2.4-blockers

 If you find more, please set Target Version to 2.4.0 and mark it a blocker. I'll try nudging
people to start closing these soon, appreciate any help!

thanks,
Arun
