> 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
