Basic settings

Properties Description

Schema and Edit Schema

  • A schema is a row description. It defines the number of fields (columns) to be processed and passed on to the next component. When you create a Spark Job, avoid the reserved word line when naming the fields.

    Click Sync columns to retrieve the schema from the previous component connected in the Job.

    Click Edit schema to make changes to the schema. If the current schema is of the Repository type, three options are available:

    • View schema: choose this option to view the schema only.

    • Change to built-in property: choose this option to change the schema to Built-in for local changes.

    • Update repository connection: choose this option to change the schema stored in the repository and decide whether to propagate the changes to all the Jobs upon completion.

      If you just want to propagate the changes to the current Job, you can select No upon completion and choose this schema metadata again in the Repository Content window.

  • Built-In: You create and store the schema locally for this component only.

  • Repository: You have already created the schema and stored it in the Repository. You can reuse it in various projects and Job designs.
Allocate Define the schema against which the data of each column must be validated.

The schema can be a local file or a HTTP protocol.

Die on error

Select the check box to stop the execution of the Job when an error occurs.

Clear the check box to skip any error and continue the Job execution process.
