An sbt plugin for launching and scheduling Oozie applications.

Table of contents


  • sbt (0.13.5+ or 1.0.0+)
  • An installation of Hadoop (>= 2.6.x) to target
  • An installation of Oozie (>= 4.0.x) to target


Add the following line to project/plugins.sbt. See the Using plugins section of the sbt documentation for more information.

addSbtPlugin("com.tapad.sbt" % "sbt-oozie" % "0.1.0")


By default, sbt-oozie assumes the OOZIE_URL environment variable is set and is pointing to the Oozie server's request endpoint (e.g. http://my-oozie-server:11000/oozie.

If the OOZIE_URL environment variable cannot be set, the Oozie server URL can be provided to the oozieUrl setting key in your build definition.

Remember to enable the OoziePlugin in your build definition, or if using a multi-project setup, on each subproject that you wish to integrate with Oozie.

hadoopClasspath := hadoopClasspathFromExecutable.value // used by sbt-hadoop, see next section of README.md

oozieUrl := "http://my-oozie-server:11000/oozie" // required iff OOZIE_URL env variable is not set


Integration with sbt-hadoop

sbt-oozie will transitively bring sbt-hadoop into your project once enabled.

sbt-hadoop is used for uploading necessary artifacts (Oozie workflow and coordinator definitions, and if necessary, application JAR files) to HDFS, or any file system or storage backend that implements the Hadoop FileSystem abstraction (e.g. Amazon S3, Google Cloud Storage).

Uploading application resources to HDFS

The oozieUpload task is used to upload a given Oozie application to HDFS for subsequent submittal, execution, or scheduling.

From the sbt project which has enabled the OoziePlugin, issue:

> oozieUpload <name of application>

Tab-completion is supported:

> oozieUpload <TAB>
baz/quux   baz/qux    foo
> oozieUpload foo
[info] Uploading foo to /oozie/applications/foo

Your application will be uploaded to the path defined by the application's oozie.wf.application.path or oozie.coord.application.path property.

Running an adhoc workflow

To run an Oozie workflow that has been uploaded to HDFS, invoke the oozieRun task.

oozieRun takes, as a parameter, the name of an application that exists in your project.

An Oozie application is any directory that exists in your project's oozieLocalApplications directory that contains a workflow.xml file.

Tab-completion is supported:

> oozieRun <TAB>
baz/quux   baz/qux    foo
> oozieRun foo
[info] 0044773-170912171845818-oozie-oozi-W

The workflow ID of your application will be printed to the log.

Scheduling a workflow for periodic execution

Scheduling an Oozie coordinator that has been uploaded to HDFS also uses the oozieRun task.

An Oozie coordinator application has the same requirements as a workflow application with the addition of also including a coordinator.xml file.

Again, oozieRun takes the name of your Oozie application as a parameter.

Tab-completion is supported:

> oozieRun <TAB>
baz/quux   baz/qux    foo
> oozieRun baz/quux
[info] 0044790-170912171845818-oozie-oozi-C

The coordinator ID of your application will be printed to the log.

Kill a running coordinator by application name or by coordinator ID using oozieKill:

> oozieKill baz/quux
> oozieKill 0044790-170912171845818-oozie-oozi-C


The twirl templating engine can be leveraged to help author Oozie applications.

NOTE: If using sbt 1.0.x, sbt-twirl requires that you use sbt version 1.0.1 or greater due to the Append instance backwards compatibility issue addressed in the release notes.

Add the following lines to project/plugins.sbt.

addSbtPlugin("com.tapad.sbt" % "sbt-oozie" % "0.1.0")

addSbtPlugin("com.tapad.sbt" % "sbt-oozie-templating" % "0.1.0")

Also be sure to enable both the sbt-oozie and the sbt-oozie-templating plugins in your build.sbt file:

enablePlugins(OoziePlugin, OozieTemplatingPlugin)

Add your twirl templates to the location specifed by oozieTemplating:sourceDirectory. By default, this location will be the templates subdirectory inside of your project's resources directory (e.g. src/main/resources/templates).

For the following example, a template with the file name workflow.scala.xml has been added to src/main/resources/templates/my_oozie_application/workflow.scala.xml. Its contents are:


The helper template is placed alongside workflow.scala.xml, in the same directory, in a file called helper.scala.xml:

@(foo: String)

Generate your Oozie application by invoking oozieEvaluateTemplates. The results from evaluating these templates will be placed in oozieTemplating:target, which by default, will be the generated subdirectory of your project's resources directory (e.g. src/main/resources/generated).

The values for the settings provided by sbt-oozie-templating, given a default build definition, can be found in the table below:

Setting key (scope:name) Default value
templating:sourceDirectory src/main/resources/templates
templating:target src/main/resources/generated

These can be customized to suit your project's structure.

Non-templated, static resources will be copied to oozieTemplating:target with no modifications made to their contents.

sbt-oozie-templating need not only be used for templating Oozie XML files. It is possible to template any type of resource and evaluate it for inclusion in your application. This is a handy way of providing boilerplate and snippets that typically would have been copied from application to application.

For more information, refer to the scripted integration test found at templating-plugin/src/sbt-test/sbt-oozie/simple.

Supporting library code and common abstractions.

Running tests

Although unit tests exist, the main features and functionality of sbt-oozie and sbt-oozie-templating are tested using sbt's scripted-plugin. scripted tests exist in the src/sbt-test directories of the sbt-oozie and sbt-oozie-templating subprojects.

To run these tests, issue scripted from an sbt session after targeting either of these subprojects:

$ sbt
> project plugin
> scripted
> project templatingPlugin
> scripted

To selectively run a single scripted test suite, issue scripted <name of plugin>/<name of test project>. e.g. scripted sbt-oozie/simple.

Please note that publishLocal will be invoked when running scripted. scripted tests take longer to run than unit tests and will log myriad output to stdout. Also note that any output written to stderr during the execution of a scripted test will result in ERROR level log entries. These log entries will not effect the resulting status of the actual test.

Releasing artifacts

sbt-oozie uses https://github.com/sbt/sbt-release. Simply invoke release from the root project to release all artifacts.
