Run in Intellij IDEA

You can run your job from IDEA locally. Run -> Edit configurations -> New Application

Option	Value
Main class	com.twitter.scalding.Tool

Program arguments	job.class.name --hdfs --param1 value --param2 value --input local-path

Note that --output is optional usually. When not specified we write to NullSource which prints to stdout.

Here is sample scalding job:

package com.sample

import com.twitter.scalding._
import com.twitter.scalding.Tsv

class SampleJob(args: Args) extends Job(args) {
  val input = args("input")
  val output = args.getOrElse("output", null)

  val results = Tsv(input).read
  //todo do something here

  if (output != null)
    results.write(Tsv(output))
  else
    results.debug.write(NullSource)
}
