Thanks everyone...that helped. I'll go ahead and edit the Wiki to clarify the expectation.
I got a successful build using: ~/code/hadoop$ mvn install -DskipTests To respond to Vinod's questions: <Which branch are you running against?> I think the answer is trunk. I obtained the source code using: git clone git://git.apache.org/hadoop.git ...and the pom.xml in my source says version 3.0.0-alpha1-SNAPSHOT, and I haven't tried to do anything with branches yet. <What errors are you seeing?> You were right--without knowing any better I was running all the unit tests....so I came across several errors...one error that I was able to fix was apparently due a newline in the etc/hosts file as I learned from https://issues.apache.org/jira/browse/HADOOP-10888. After my fix, a subsequent build passed that unit test. But then a subsequent build to that build caused that same error again, even thought the newline was fixed. Another error I got when running mvn install without -DskipTests is described in https://issues.apache.org/jira/browse/HADOOP-12611. This is the type of error I thought would be worthy of ignoring. Thanks again for your time--much appreciated! -Martin On Tue, Jul 26, 2016 at 1:27 PM, Sean Busbey <bus...@cloudera.com> wrote: > The current HowToContribute guide expressly tells folks that they > should ensure all the tests run and pass before and after their > change. > > Sounds like we're due for an update if the expectation is now that > folks should be using -DskipTests and runs on particular modules. > Maybe we could instruct folks on running the same checks we'll do in > the automated precommit builds? > > On Tue, Jul 26, 2016 at 1:47 PM, Vinod Kumar Vavilapalli > <vino...@apache.org> wrote: > > The short answer is that it is expected to pass without any errors. > > > > On branch-2.x, that command passes cleanly without any errors though it > takes north of 10 minutes.
