Hi @ajaybabum, Yes we can able run Spark in local mode against the Kerberized cluster. For a quick test, can you directly open spark-shell to try reading the CSV file from the HDFS location and show the output of the contents to verify whether do you have any issue in the Cluster / Spark configuration or if it's more on your application code? >>  Will it possible in local mode without run kinit command before spark-submit. -- By passing --keytab --principal details in your spark-submit, you don't need to run kinit command before spark-submit.  Thanks  ...
