Vote has passed with 7 binding +1 from : Hitesh Shah, Luciano Resende, Sam Ruby, Chris A Mattmann, Jim Jagielski, Reynold Xin, Steve Loughran and 2 non-binding +1 from Sree V, Luke Han.
There is an issue with the project name, see discussion at [1]. We will be identifying a new name for the project before we start creating the project infrastructure. I will update the vote thread with the project new name for historical reasons. [1] https://www.mail-archive.com/general@incubator.apache.org/msg52224.html Thank you.
