## proof of concept on hadoop:

This seemed to work:

    yarn jar tutorial/execution-tutorial/target/scala-2.11/execution-tutorial-assembly-0.18.0-SNAPSHOT.jar Tutorial1 --hdfs --input test_cdx --output test_scalding_out1

Or, with actual files on hadoop:

    yarn jar tutorial/execution-tutorial/target/scala-2.11/execution-tutorial-assembly-0.18.0-SNAPSHOT.jar Tutorial1 --hdfs --input hdfs:///user/bnewbold/dummy.txt --output hdfs:///user/bnewbold/test_scalding_out2

Horray! One issue with this was that building scalding took *forever* (meaning
30+ minutes).

## sbt

Uncommenting this line in scalding:build.sbt sped things way up (don't need to
run *all* the tests):

       // Uncomment if you don't want to run all the tests before building assembly
       // test in assembly := {},

Also get the following error (in a different context):

## resources/tutorials

Whole bunch of example commands (sbt, maven, gradle) to build scalding:
