These properties are used to configure tJMSInput running in the Spark Streaming Job framework.

The Spark Streaming tJMSInput component belongs to the Messaging family.

The component in this framework is available in Talend Real Time Big Data Platform and Talend Data Fabric.

Basic settings

Module List

Select the library to be used from the list.

Context Provider

Type in the context URL, for example com.tibco.tibjms.naming.TibjmsInitialContextFactory. However, be careful, the syntax can vary according to the JMS server used.

Server URL

Type in the server URL, respecting the syntax, for example tibjmsnaming://localhost:7222.

Connection Factory JDNI Name

Type in the JDNI name.

Use Specified User Identity

If you have to log in, select the check box and type in your login and password.

To enter the password, click the [...] button next to the password field, and then in the pop-up dialog box enter the password between double quotes and click OK to save the settings.

Message Type

Select the message type, either: Topic or Queue.

Message From

Type in the message source, exactly as expected by the server; this must include the type and name of the source. e.g.: queue/A or topic/testtopic

Note that the field is case-sensitive.

Timeout for Next Message (in sec)

Type in the number of seconds before passing to the next message.

Maximum Messages

Type in the maximum number of messages to be processed.

Message Selector Expression

Set your filter.

Processing Mode

Select the processing mode for the messages.

Raw Message or Message Content

Schema and Edit Schema

A schema is a row description. It defines the number of fields (columns) to Repository. When you create a Spark Job, avoid the reserved word line when naming the fields.

The schema of this component is read-only. You can click Edit schema to view the schema.

Advanced settings

Use SSL/TLS

Select this check box to enable the SSL or TLS encrypted connection.

Then you need to use the tSetKeystore component in the same Job to specify the encryption information.

For further information about tSetKeystore, see tSetKeystore.

Properties

Click the plus button underneath the table to add lines that contains username and password required for user authentication.

Usage

Usage rule

This component is used as a start component and requires an output link.

This component, along with the Spark Streaming component Palette it belongs to, appears only when you are creating a Spark Streaming Job.

Note that in this documentation, unless otherwise explicitly stated, a scenario presents only Standard Jobs, that is to say traditional Talend data integration Jobs.

Spark Connection

You need to use the Spark Configuration tab in the Run view to define the connection to a given Spark cluster for the whole Job. In addition, since the Job expects its dependent jar files for execution, you must specify the directory in the file system to which these jar files are transferred so that Spark can access these files:
  • Yarn mode: when using Google Dataproc, specify a bucket in the Google Storage staging bucket field in the Spark configuration tab; when using other distributions, use a tHDFSConfiguration component to specify the directory.

  • Standalone mode: you need to choose the configuration component depending on the file system you are using, such as tHDFSConfiguration or tS3Configuration.

This connection is effective on a per-Job basis.
