Signatures, license, etc. look good. I'm getting some fairly
consistent failures using Java 7 + Ubuntu 15 + "-Pyarn -Phive
-Phive-thriftserver -Phadoop-2.6" -- does anyone else see these? they
are likely just test problems, but worth asking. Stack traces are at
the end.
There are currently 79 issues targeted for 1.5.0, of which 19 are
bugs, of which 1 is a blocker. (1032 have been resolved for 1.5.0.)
That's significantly better than at the last release. I presume a lot
of what's still targeted is not critical and can now be
untargeted/retargeted.
It occurs to me that the flurry of planning that took place at the
start of the 1.5 QA cycle a few weeks ago was quite helpful, and is
the kind of thing that would be even more useful at the start of a
release cycle. So would be great to do this for 1.6 in a few weeks.
Indeed there are already 267 issues targeted for 1.6.0 -- a decent
roadmap already.
