Hi Andrew, >> I'm trying HEAD of branch-0.11.
You need PIG-3248: https://issues.apache.org/jira/browse/PIG-3248. It's not in branch-0.11 but in trunk. In particular, you need to add the following lines to ivy.xml: + <dependency org="org.apache.hadoop" name="hadoop-yarn-client" + rev="${hadoop-mapreduce.version}" conf="hadoop23->master"/> Thanks, Cheolsoo On Sun, May 12, 2013 at 7:13 PM, Andrew Purtell <apurt...@apache.org> wrote: > It happens consistently on multiple systems and different operating systems > and JDK versions, so while is a build (or more specifically a unit test > environment) problem, it is unlikely an issue singular to me. > > On Saturday, May 11, 2013, Konstantin Boudnik wrote: > > > As you know we've been testing Pig 0.11 vs 2.0.4-alpha as a part of > > Bigtop's > > validation for the latest hadoop release and it worked ok.
