John Lonergan commented on SPARK-12312:
---------------------------------------
Yes - the driver wrapper I wrote accepted both a KT or a ticket cache.,
See the reference I gave.
If I recall correctly we provided the option of selecting either approach
of ...
UserGroupInformation.loginUserFromKeytabAndReturnUGI(principal, keytabFile)
OR
UserGroupInformation.getUGIFromTicketCache(principal, cache)

> 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.
