Hi developers, I have enabled kerberos on my cluster although cluster is green and running but i'm not able to access hdfs even after generating ticket.The error is same as the ticket is'nt generated. Probably authenticated server is not authenticating my ticket. Here is the error. "19/05/16 08:53:07 WARN ipc.Client: Exception encountered while connecting to the server : org.apache.hadoop.security.AccessControlException: Client cannot authenticate via:[TOKEN, KERBEROS] ls: Failed on local exception: java.io.IOException: org.apache.hadoop.security.AccessControlException: Client cannot authenticate via:[TOKEN, KERBEROS]; Host Details : local host is: "FQDN/X.X.X.X"; destination host is: "FQDN":PORT;" Thanks.

hy @Hamza, if you are using no security protocol like kerberos/tsl then do use kafka processor version less than 0.9 which is getkafka and for those having kerberos security installed must have to use version above than 0.9 like consumekafka 0.10 and above.Its mandatroy.
