Javadoc for network-common fails. This causes sbt publish-local to fail, and not deliver the spark-network-common jar/module to the local publish location. This in turns causes applications which are assembled using locally linked Spark to fail building.
1. Checkout master branch
2. sbt publish-local
3. Note javadoc errors
4. Navigate to ~./ivy2/local/org.apache.spark or equivalent
5. spark-network-common_2.10 should be missing
6. Building application with sbt assemble against local linked spark then fails since network-common is missing.
I confirmed the problem is the javadoc compilation failure by fixing all javadoc errors with placeholder "TODO"s. Confirmed fix by running the above steps which work correctly.
