-- sbt? or gradle? (build tool)

-       (or just a single .deb...)
-- scalding (mapreduce framework)
-- scala (java also fine?)
-    => will scala work with java 1.7?
-    => scala 2.11 (~2014) works with java 7; scala 2.12 and up require 8

-    => ubuntu xenial: scala/xenial 2.11.6-6
-    => "Scalding works with Scala 2.10 and 2.11 is recommended"
-- testing
-- hbase connector library
-    => maybe spyglass?

-## 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).
-
-potentially instead:
-
-    hadoop jar scald-mvp-assembly-0.1.0-SNAPSHOT.jar com.twitter.scalding.Tool main.scala.example.WordCountJob --hdfs --input hdfs:///user/bnewbold/dummy.txt --output hdfs:///user/bnewbold/test_scalding_out2
-
-Hypothesis: class name should be same as file name. Don't need `main` function
-if using Scalding Tool wrapper jar. Don't need scald.rb.
-
-    hadoop jar scald-mvp-assembly-0.1.0-SNAPSHOT.jar com.twitter.scalding.Tool example.WordCount --hdfs --input hdfs:///user/bnewbold/dummy.txt --output hdfs:///user/bnewbold/test_scalding_out2

-## 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):
-
-    bnewbold@orithena$ sbt new typesafehub/scala-sbt

-## resources/tutorials
-
-Whole bunch of example commands (sbt, maven, gradle) to build scalding:
