Hadoop Streaming Error Codes

Published: 2011-01-31 08:12 UTC. Tags: hadoop

I'm using Hadoop Streaming a lot. It's exit codes has been something of a mystery, so today I decided to find out by looking at the source code.

The exit codes are listed in StreamJob.java, and are as follows:

  1. Success
  2. Job not successful, i.e. something went wrong with M/R code.
  3. Bad input path
  4. Invalid jobconf
  5. Output path already exists
  6. Error launching job. Could be any error, for example some HDFS communication error.
