> Support for non-standard krb5.conf via KRB5_CONFIG variable
> -----------------------------------------------------------
>
> Key: SPARK-12050
> URL: https://issues.apache.org/jira/browse/SPARK-12050
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 1.5.2
> Environment: Linux
> Reporter: Hari Krishna Dara
> Priority: Minor
> Attachments: SPARK-12050-patch.diff
>
>
> For environments with non-standard location of krb5.conf, most native
> kerberos implementations support KRB5_CONFIG environment variable specifying
> the location. Java doesn't recognize this environment variable, but supports
> java.security.krb5.conf system property for the same.
> Since environment variables can be accessed in Java, Spark should include the
> system property on the command-line while the launcher command-line is built
> and add support for custom krb5.conf location and make this seamless. This
> variable can then go into the spark-env.sh.
