-------------------------------
> Flink shouldn't require Kerberos credentials
> --------------------------------------------
>
> Key: FLINK-5361
> URL: https://issues.apache.org/jira/browse/FLINK-5361
> Project: Flink
> Issue Type: Bug
> Components: Client
> Reporter: Eron Wright
> Assignee: Eron Wright
> Labels: kerberos, security
> Fix For: 1.2.0, 1.3.0
>
>
> The behavior since FLINK-3929 has been to fail if Hadoop security is enabled
> but a Kerberos credential (or delegation token) isn't available. It should
> proceed with a warning that a credential isn't available.
> For example, say your shell has a HADOOP_CONF_DIR variable that points to a
> secure Hadoop installation. Say you'd like to use Flink for a completely
> unrelated reason (not involving Hadoop). The Flink CLI will fail at startup
> with a message to the effect that a kerberos ticket is needed. A ticket
> should not be needed in this scenario.
