@mark-bathori I tested the change and I still get an error. Could you please double check it?
My scenario:

• start PutIceberg (1) processor connecting to unsecure HDFS/Hive
• load data with PutIceberg (1) => success
• start another PutIceberg (2) processor connecting to secured HDFS/Hive using Kerberos
• load data with PutIceberg (1) => failure
