[jira] [Commented] (SPARK-12050) Support for non-standard krb5.conf
via KRB5_CONFIG variable
[ https://issues.apache.org/jira/browse/SPARK-12050?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15034243#comment-15034243 ]
Hari Krishna Dara commented on SPARK-12050:
-------------------------------------------
Actually, I found that SPARK_SUBMIT_OPTS can be already used to pass options like this via spark-env.sh, so this change is not really required.

> 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.
