Oozie Workflow Activity properties
Use the Oozie Workflow Activity stage to invoke Oozie workflows from the Designer client. Oozie workflows are a collection of actions that are arranged in a control dependency. These actions are computation tasks that are written in Jaql, MapReduce, or other frameworks that you use to write applications to process large amounts of data.
Attention: This stage can be installed
on Red Hat Linux 64-bit systems only.
The Oozie
Workflow Activity stage contains the following fields:
- Oozie Server
- Specify the URL for the Oozie server to connect to. For example, http://myserver:8280/oozie,
where myserver is the name of the Oozie server
that you are connecting to. The port number
8020
is used for InfoSphere BigInsights, but differs depending on the Hadoop system that you use. - Workflow Definition Path
- Enter the location of the workflow definition that you want to run. A workflow definition is a programmatic description of a workflow in XML format.
- Do not checkpoint job run
- Select this option to specify that checkpoint information will not be recorded for this activity. This option specifies that if an activity later in the sequence fails, and the sequence is restarted, this activity will run again, regardless of whether it finished successfully in the original run. This option is only available if checkpoint information is recorded for the entire sequence job.
- Workflow Parameters
- Enter values for any parameters that the activity requires. The
grid displays all parameters that are expected by the activity.
- Name
- Type a name for your parameter.
- Value Expression
- Type an expression that specifies a value for the parameter. Literal values must be enclosed in inverted commas.
