Eron Wright created FLINK-5361:
-----------------------------------
Summary: 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
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.
