Bah, typos. Can those other patches be looked at and planned for
inclusion into a release?

I'm in agreement with Steve on this one. We're aware that Java 6 is EOL,
but we can't drop support for the lifetime of the 2.x line since it's a
(very) incompatible change. AFAIK a 3.x release fixing this isn't on
any of
our horizons yet.
Best,

most (all?) of these are pom changes
A good number are basically pom changes to update to newer versions of
dependencies. A few, such as commons-math3, required code changes as
well
because of a namespace change. Some are minor code changes to enhance
compatibility with newer dependencies. Even tomcat is mostly changes in
pom files.
Most of the changes are minor. There are 2 big updates though:
Jetty 9
(which requires java 7) and tomcat 7. These are also the most
difficult
patches to rebase when hadoop produces a new release.
that's not going to go in the 2.x branch. Java 6 is still a common
platform
that people are using, because historically java7 (or any leading edge
java
version) is buggy.
that said, our QA team did test hadoop 2 & HDP-2 at scale on java7 and
openjdk 7, so it all works -it's just the commit "java7 only" is a big
decision that
I realize moving to java 7 is a big decision and wasn't trying to imply
this should happen without discussion and planning, just that it
would be
nice to have the discussion and see where things land. It can also help
minimize work. There is an open bz for updating jetty to jetty 8
(the last
version that would work on java 6), but if there are plans to move to
java7, maybe it makes sense to just to jetty 9 and not test a new
version
of jetty twice.
With Hadoop in Fedora running on these newer deps there is a test bed to
play with to give some level of confidence before taking the plunge
on any
major change.
