             Summary: Kerberos configuration error when using short names in multiple HDFS Sinks
                 Key: FLUME-2749

    Affects Versions: v1.6.0
            Reporter: Johny Rufus
            Assignee: Johny Rufus


When we have more thank one HDFS Sink, configured in kerberos mode, and principal is configured with a short name like 'flume' (without the @REALM information), we get a 

java.lang.IllegalStateException: Cannot use multiple kerberos principals in the same agent.  Must restart agent to use new principal or keytab. Previous = flume@EXAMPLE.COM (auth:KERBEROS), New = flume
