[jira] [Created] (FLINK-6608) Relax Kerberos login contexts parsing by trimming whitespaces in contexts list

Tzu-Li (Gordon) Tai created FLINK-6608:
------------------------------------------

             Summary: Relax Kerberos login contexts parsing by trimming whitespaces in contexts list
                 Key: FLINK-6608
                 URL: https://issues.apache.org/jira/browse/FLINK-6608
             Project: Flink
          Issue Type: Improvement
          Components: Configuration, Security
            Reporter: Tzu-Li (Gordon) Tai
            Assignee: Tzu-Li (Gordon) Tai
            Priority: Minor
             Fix For: 1.3.0, 1.4.0


The Kerberos login contexts list parsing right now isn't quite user-friendly.
The list must be provided as: {{security.kerberos.login.contexts: Client,KafkaClient}}, without any whitespace in between.

We can relax this to be more user-friendly by trimming any whitespaces in the list.

A user actually stumbled across this: http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/Problems-with-Kerberos-Kafka-connection-in-version-1-2-0-td12580.html#a12589
