As a security measure to prevent accidental or malicious modification of Jobs, from Talend 7.1 onwards, when saving a task or receiving a generated Job from the Talend CommandLine, the Talend JobServer will verify whether it has a valid signature before running it. You will need to migrate existing unsigned Jobs within a grace period of 90 days upon setting your license for Talend Administration Center, or set a migration token for them if you still want to run or migrate them after the grace period.
This job was created by an unsupported version of Talend Studio. Talend cannot guarantee the origin of such artifacts which may pose a security risk to your system. Please contact Talend Support for further details about supported versions and our support policies.
