> We need to clean up warnings in the maven logs.  They seem to have piled up recently;
some are about scala lib version conflicts, some are about deprecated APIs, some are about
code style.
> Some may be fine for now but extra warnings in build logs feels like bad hygiene to me.
> Some examples:
> [WARNING]  Expected all dependencies to require Scala version: 2.10.3
> [WARNING]  com.twitter:chill_2.10:0.3.1 requires scala version: 2.10.0
> [WARNING] Multiple versions of scala libraries detected!
> [WARNING] /home/akm/mahout/spark/src/main/scala/org/apache/mahout/sparkbindings/drm/CheckpointedDrmBase.scala:73:
warning: a pure expression does nothing in statement position; you may be omitting necessary
parentheses
> [INFO]     this
> [WARNING]  Expected all dependencies to require Scala version: 2.10.3
> [WARNING]  org.apache.mahout:mahout-math-scala:1.0-SNAPSHOT requires scala version: 2.10.3
> [WARNING]  org.scalatest:scalatest_2.10:2.0 requires scala version: 2.10.0
> [WARNING] Multiple versions of scala libraries detected!
> [WARNING] /home/akm/mahout/math-scala/src/main/scala/org/apache/mahout/math/scalabindings/package.scala:132:
warning: non-variable type argument Double in type pattern Iterable[Double] is unchecked since
it is eliminated by erasure
> [INFO]         case t: Iterable[Double] => t.toArray
> [WARNING] /home/akm/mahout/examples/src/main/java/org/apache/mahout/clustering/syntheticcontrol/kmeans/Job.java:
Some input files use or override a deprecated API.
> [WARNING] /home/akm/mahout/examples/src/main/java/org/apache/mahout/clustering/syntheticcontrol/kmeans/Job.java:
Recompile with -Xlint:deprecation for details.
