Minor Description
The Maven-based builds in the build matrix have been failing for a few days:
https://amplab.cs.berkeley.edu/jenkins/view/Spark/
On inspection, it looks like the Spark SQL Java tests don't compile:
I confirmed it by repeating the command vs master:
mvn -Dhadoop.version=1.0.4 -Dlabel=centos -DskipTests clean package
The problem is that this module doesn't depend on JUnit. In fact, none of the modules do, but com.novocode:junit-interface (the SBT-JUnit bridge) pulls it in, in most places. However this module doesn't depend on com.novocode:junit-interface
Adding the junit:junit dependency fixes the compile problem. In fact, the other modules with Java tests should probably depend on it explicitly instead of happening to get it via com.novocode:junit-interface, since that is a bit SBT/Scala-specific (and I am not even sure it's needed).
