We have all been there. You create a job with a tMap and it fails due to some problem in the tMap config. Many times it is due to something connected to data being null. Maybe you have a "compareTo" checking a String that is null or a "parseInt" trying to convert some non-numeric text to an Integer. They are common issues, but they are generally pretty tricky to identify so that you can cater for situations in which they occur. That is if you do not use a trick that is very useful and surprisingly very rarely used. Talend actually provide a mechanism to help you pinpoint these issues, but for some reason they do not publicise it well. This post will show you how to use it.
Thank you very much !! It helped a lot ! Talend needs more articles like that on official page.
Thanks for the feedback @novosartovt. I am working on more pieces like these and will add them to my blog section of the Talend website https://www.talend.com/blogger/rhall/. However, in the meantime, we do have a pretty useful knowledge base of articles written by Talend experts here: https://community.talend.com/t5/Community-Knowledge/ct-p/tld_knowledge_base
Thank you for the links!
