Question

Explain the error handling in Talend.

Answer 1

There are few ways in which errors in Talend can be handled:

• For simple Jobs, one can rely on the exception throwing process of Talend Open Studio, which is displayed in the Run View as a red stack trace.
• Each Subjob and component has to return a code which leads the additional processing.  The Subjob Ok/Error and Component Ok/Error links can be used to direct the error towards an error handling routine.
• The basic way of handling an error is to define an error handling Subjob which should execute whenever an error occurs.
