Devaraj Kavali commented on SPARK-31800: ---------------------------------------- If we look at the log, about *krb5.conf* is just an info log but not the actual cause for failure. Actual failure is about the *spark.kubernetes.file.upload.path*, you can provide any dfs(S3, HDFS or any distributed file system) path for the config. > Unable to disable Kerberos when submitting jobs to Kubernetes > ------------------------------------------------------------- > > Key: SPARK-31800 > URL: https://issues.apache.org/jira/browse/SPARK-31800 > Project: Spark > Issue Type: Bug > Components: Kubernetes > Affects Versions: 3.0.0 > Reporter: James Boylan > Priority: Major > > When you attempt to submit a process to Kubernetes using spark-submit through > --master, it returns the exception: > {code:java} > 20/05/22 20:25:54 INFO KerberosConfDriverFeatureStep: You have not specified > a krb5.conf file locally or via a ConfigMap.
