Description:
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.
