Qlik Talend Studio Snowflake JAR error: java.lang.NoClassDefFoundError

[Sainadh_Moole]

The Qlik Talend Studio job execution failed with code 1 and the error message:

Job stopped with errors or unable to run. Exception in thread "main" java.lang.NoClassDefFoundError: net/snowflake/client/loader/LoadResultListener

This indicates that Qlik Talend Studio could not find the required Snowflake client class during runtime.

Resolution

Replace the JAR with a fresh Snowflake JDBC driver (snowflake-jdbc.jar). 

See the following guides for details:

• Ways to install external modules 
• tLibraryLoad: Loads useable Java libraries in a Job

Cause

The error NoClassDefFoundError occurs when a Java class is missing from the runtime environment.

In this case, the Snowflake JAR file bundled with the older Qlik Talend Studio version did not include the LoadResultListener class, indicating a corrupted JAR file.

This mismatch between Qlik Talend Studio and the Snowflake connector causes the job to stop unexpectedly.

Environment
