azkaban 0.6.18

AzkabanCLI

AzkabanCLI

A lightweight Azkaban client providing:

• A command line interface to run workflows, upload projects, etc.

• A convenient and extensible way for building projects.

Sample

Below is a simple configuration file for a project containing a workflow with four pig scripts.

from azkaban import PigJob, Project
from getpass import getuser

PROJECT = Project('sample', root=__file__)

# properties available to all jobs
PROJECT.properties = {
  'user.to.proxy': getuser(),
  'param': {
    'input_root': 'sample_dir/',
    'n_reducers': 20,
  },
  'jvm.args.mapred': {
    'max.split.size': 2684354560,
    'min.split.size': 2684354560,
  },
}

# list of pig jobs
JOBS = [
  {'pig.script': 'first.pig'},
  {'pig.script': 'second.pig', 'dependencies': 'first.pig'},
  {'pig.script': 'third.pig', 'param': {'foo': 48}},
  {'pig.script': 'fourth.pig', 'dependencies': 'second.pig,third.pig'},
]

for option in JOBS:
  PROJECT.add_job(option['pig.script'], PigJob(option))

The examples directory contains another sample project that uses Azkaban properties to build a project with two configurations: production and test, without any job duplication.
