Talend Studio includes the Apache logging utility Log4j to provide logging at runtime. You can enable or disable Log4j loggers in components and customize the Log4j configuration globally for the project.

Warning: Following the Log4j2 security issue, make sure to disable Log4j loggers in components when you run Spark Batch and Spark Streaming Jobs with Azure Synapse and HD Insight 4.0 distributions. To avoid any Job failure, clear the Activate log4j in components check box from the Log4j view in File > Edit Project Properties > Project Settings.

Procedure

  1. On the toolbar of the Studio main window, click or click File > Edit Project Properties from the menu bar to open the Project Settings dialog box.
  2. In the tree view of the dialog box, click the Log4j node to open the Log4j view.
  3. Select the Activate log4j in components check box to activate the Log4j feature.

    By default, the Log4j feature is activated and Log4j 2 is enabled when a project is created.

    When a project is imported from Talend 7.2 or an earlier version, which only supports Log4j 1, the deprecated Log4j 1 is selected from the Log4j version drop-down list by default. All POM files for the project will be synchronized when you change the Log4j version.

    Note: If you need to deploy your Jobs to Talend Cloud, the use of Log4j 2 requires Talend Remote Engine 2.8.1 or higher.
  4. If needed, change the global Log4j configuration by modifying the XML instructions in the Log4j template area.
    For example, to configure the root logger for Log4j 2 to output all debug or higher messages, go to the Loggers section and set the value of the level attribute of the root node to debug.

    For more information, see Log4j 2 configuration.

    For more information, see Log4j 1 configuration.
