John Lonergan commented on SPARK-12312:
---------------------------------------
I think we fixed this in oracle along the lines of this post...
https://stackoverflow.com/questions/52662249/javakerberos-authentication-to-sql-server-on-spark-framework
See the references to datamountaineer and also the git repo mentioned gives
good ideas...

You should be able to get it working for oracle as I have. We followed
pretty much the same approach as ...
https://github.com/nabacg/krb5sqljdb/blob/master/src/main/scala/net/cabworks/jdbc/Krb5SqlServer.scala
.... but we used java and oracle rather than scala and mssql
It was fairly straightforward.

> JDBC connection to Kerberos secured databases fails on remote executors
> -----------------------------------------------------------------------
>
> Key: SPARK-12312
> URL: https://issues.apache.org/jira/browse/SPARK-12312
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 1.5.2, 2.4.2
> Reporter: nabacg
> Assignee: Gabor Somogyi
> Priority: Minor
>
> When loading DataFrames from JDBC datasource with Kerberos authentication,
> remote executors (yarn-client/cluster etc. modes) fail to establish a
> connection due to lack of Kerberos ticket or ability to generate it.
> This is a real issue when trying to ingest data from kerberized data sources
> (SQL Server, Oracle) in enterprise environment where exposing simple
> authentication access is not an option due to IT policy issues.
