Hi, I have HDP 2.6.4 sandbox, most of the services like HDFS, HIVE etc kerberized and test connection on Ranger also works. But using MIT Kerberos client on my Windows, get ticket is failing with an error "Ticket initialization failed. Kerberos 5: Cannot contact any KDC for requested realm(error -1765328228)". I have provided Principal as "hive/sandbox-hdp.hortonworks.com@HDFSCLUSTER.COM" Using putty and ssh port 2222, I can see "172.17.0.2 sandbox-hdp.hortonworks.com sandbox-hdp" in /etc/hosts file. But this host sandbox-hdp.hortonworks.com as well as the ip 172.17.0.2 is not pingable from my Windows: C:\Windows\System32>ping 172.17.0.2 Pinging 172.17.0.2 with 32 bytes of data: Reply from 122.181.1.205: Destination host unreachable. Reply from 122.181.1.205: Destination host unreachable. Reply from 122.181.1.205: Destination host unreachable. Request timed out. I think the hostname in the principal is not pingable and hence failing to get the ticket. I am trying to troubleshoot this problem for the past couple of days. I am not sure what I am missing, anyone please help me. Thanks , Tulasi ... View more
