> In the SparkSubmit code, we call {{resolveGlobPaths}}, which eventually calls
> {{getFileStatus}}, which for HDFS is an RPC call to the NameNode:
> https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/deploy/SparkSubmit.scala#L346.
> We do this before we call {{loginUserFromKeytab}}, which is further down in
> the same method:
> https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/deploy/SparkSubmit.scala#L655.
> The result is that the call to {{resolveGlobPaths}} fails in secure clusters
> with:
> {code}
> javax.security.sasl.SaslException: 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.
