You have at least one error showing that you do not have winutils.exe installed on your machine. This question and preferred answer should help you....

Seems to do with authentication. I see many indications, and this one in particular: java.io.IOException: Login failure for bob@D2-TDBFG.COM from keytab /home/bob/bob Is that keytab file accessible for this user? When the job is launched, who is the user that launched it? Shell user? jobserver? If you are running from studio, most likely you will have problem. Usually kerberos is not explicitly installed on the studio desktop, however I have done it in the past. Get with your cluster admin about this.

Hello,

For more information on the cause of this problem, please see the TalendHelpCenter:The missing winutils.exe program in the Big Data Jobs page.
