I will add my two cents in here on the diversity front as a member of the
Pig team which has been working closely with Tez team for the past 3

 There has been a whole lot of features and design changes done in Tez
driven by requirements from Pig and it has been a pleasure working with the
Tez community. We have had a really good collaboration and development has
happened at a really really fast pace both in Pig and Tez, with Pig team
picking features from Tez snapshot builds as and when they are fixed. We
just merged Pig on Tez branch into Pig trunk last month. Most of the
collaboration has been through jiras and you can see a lot of linked Pig
jiras. Pig on Tez is especially a cross-company team effort in Apache -
Yahoo!, Hortonworks, Netflix and LinkedIn and many of the requirements and
fixes on Tez has been driven by the security, performance and large scale
needs of these companies. is the list of Tez
jiras created just by the Pig team (48 jiras). There were at least quite a
few more created by others when we reported issues in mails.

 Hive of course is the other big project and Cascading is also into the mix
now. With all the widely adopted analytics tools on top of Hadoop adding
support for it and many companies adopting it there is very good future for
Tez and I think it is just prejudice to call it as a commercial development
masquerading as an Apache community. We really see it as a replacement for
mapreduce in the near term and pleased with the current results and the
future potential as a user and have been investing in the development of
Tez as well with dedicated resources. We opened Pig and Hive on Tez for
testing for users in Yahoo! in Apr and Cheolsoo opened up Pig on Tez for
users in Netflix this month and both Netflix and Y! have plans to get it
into production by end of the year and Linkedin also hopes to do the same.
With this early adoption from some of the biggest users of hadoop, I am
sure Tez will only become more stable and mature in the coming year and
gain more traction and wider adoption with other users as well as more
companies migrate to Hadoop 2.
