Talend Remote Engine v2.13.13

New features

Feature	Description
SSL communication	The engine installer now provides an option to automatically enable Secure Sockets Layer (SSL) communication between Talend Remote Engine and its JobServer, simplifying the SSL setup process. For further information, see the SSL setup step in Installing the Remote Engine automatically.
SSH password	The engine installer can generate a strong password for SSH communication with Talend Remote Engine. You can manually update this password. For more information, see the SSH-related step in Installing the Remote Engine automatically.

Notable fixes

Issues	Description
DPE-1047	Fixed an issue where Job executions failed after a Remote Engine upgrade due to a missing GPG path (SUPPORT-3386).
DPE-1346	Upgraded org.ops4j.pax.url:pax-url-aether to version 2.6.17, resolving a Remote Engine restart issue triggered by a Java heap space OutOfMemoryError (SUPPORT-3868).
DPE-1273	Addressed a problem where CBP (capacity-based pricing) metrics were not sent. This problem triggered the restart of all microservices on Remote Engine v2.13.11 (SUPPORT-4144).

Deprecated and removed items

Feature	Description
Token refresh for Box connection	Native support for the Box connector was removed from Talend Management Console in the R2025-05 release. As a result, automatic token refresh for Box connections is no longer supported and removed from Talend Remote Engine. For more information on managing connections in Talend Management Console, see Connection or Managing connections.

Known issues

Issues Description

Hanging engine CLI

Issues	Description
Hanging engine CLI	The Talend Remote Engine CLI stops responding after an amount of time. Steps to reproduce: Start the engine using <RE_HOME>/bin/karaf or <RE_HOME>/bin/trun. Pair the engine (issue only occurs when paired). Run Jobs or leave the engine idle. After a delay, the CLI hangs. This issue is observed following the Karaf upgrade to version 4.4.7. However, Only the CLI is affected. It does not occur when installing the engine as a system service using the installer. Regular engine functions, such as task execution, logging, and metrics, remain unaffected. To resolve the hanging CLI issue, restart the engine after pairing to restore access to the Karaf console.
SSL error	An SSL error occurs during data integration task deployment when all of the following conditions are met: Use the installer to install Talend Remote Engine. During installation, select Install as a system service. During installation, select Use SSL for JobServer communication to enable SSL automatically. Start Talend Remote Engine using the shell scripts from the bin folder. Run data integration tasks with the engine. Task execution fails with an error message similar to the following: `Execution 8720a57b-d454-420d-b894-ba768f8a24c4 failed with code -1 and \ error org.talend.remote.commons.exception.ClientServerException: \ javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure` This occurs because the automated SSL setup for a Talend Remote Engine service is not designed to be used with the shell scripts. To avoid this issue, do not use the shell scripts to start the engine service, use the usual way instead: On Windows, use its services management console, services.msc, or run the command net start Talend-Remote-Engine. On Linux, run the command systemctl start talend-remote-engine.

The Talend Remote Engine CLI stops responding after an amount of time.

Steps to reproduce:

Start the engine using <RE_HOME>/bin/karaf or <RE_HOME>/bin/trun.
Pair the engine (issue only occurs when paired).
Run Jobs or leave the engine idle. After a delay, the CLI hangs.

This issue is observed following the Karaf upgrade to version 4.4.7.

However, Only the CLI is affected. It does not occur when installing the engine as a system service using the installer. Regular engine functions, such as task execution, logging, and metrics, remain unaffected.

To resolve the hanging CLI issue, restart the engine after pairing to restore access to the Karaf console.

SSL error

An SSL error occurs during data integration task deployment when all of the following conditions are met:

Use the installer to install Talend Remote Engine.
During installation, select Install as a system service.
During installation, select Use SSL for JobServer communication to enable SSL automatically.
Start Talend Remote Engine using the shell scripts from the bin folder.
Run data integration tasks with the engine.

Task execution fails with an error message similar to the following:

Execution 8720a57b-d454-420d-b894-ba768f8a24c4 failed with code -1 and \
error org.talend.remote.commons.exception.ClientServerException: \
javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure

This occurs because the automated SSL setup for a Talend Remote Engine service is not designed to be used with the shell scripts.

To avoid this issue, do not use the shell scripts to start the engine service, use the usual way instead:

On Windows, use its services management console, services.msc, or run the command net start Talend-Remote-Engine.
On Linux, run the command systemctl start talend-remote-engine.
