>                 Key: SPARK-22319
>                 URL:
>             Project: Spark
>          Issue Type: Bug
>          Components: Deploy, Spark Core
>    Affects Versions: 2.2.0, 2.3.0
>            Reporter: Steven Rand
>            Assignee: Steven Rand
>             Fix For: 2.3.0
> In the SparkSubmit code, we call {{resolveGlobPaths}}, which eventually calls {{getFileStatus}},
which for HDFS is an RPC call to the NameNode:
> We do this before we call {{loginUserFromKeytab}}, which is further down in the same
> The result is that the call to {{resolveGlobPaths}} fails in secure clusters with:
> {code}
> GSS initiate failed [Caused by GSSException: No valid
credentials provided (Mechanism level: Failed to find any Kerberos tgt)]
> {code}
> A workaround is to {{kinit}} on the host before using spark-submit. However, it's better
if this workaround isn't necessary. A simple fix is to call loginUserFromKeytab before attempting
to interact with HDFS.
> At least for cluster mode, this would appear to be a regression caused by SPARK-21012.
