Hi @pvillard, I have some doubts about what kind of keytab file to create. I don't know much about Kerberos and do not find much information about the kind of Keytab file I should use to connect my Nifi Cluster to a kerberized Cloudera Cluster. Can you help me? ... View more

Make sure your realm name is all uppercase characters. hdfs-hadoopprod@Hortonworks.com should really be hdfs-hadoopprod@HORTONWORKS.COM. Also, the default settings are for the headless/user principal names to include the cluster name. If you choose to stay with this, make sure the clusters have unique names. However, you are welcome to change the unique value for these principal names to anything that avoids a collisions. If principals names are the same in multiple Ambari-managed clusters using the same KDC, one instance of Ambari will wind up changing the passwords out from under the other other instances. This will invalidate the keytab files installed on the hosts and break the clusters. ... View more

Pig is definitely and option, but a couple points. If you only do this once a month and have all the daily files (say 1st - 31st of the month) then understand that Pig doesn't do simple control loop logic (as identified in the presentation that my answer above points you to) and you'd have to wrap it with some controlling script or something. But... on the other hand... if you get a new daily file each day then Pig is going to be your best friend since the previous day's finalized file is now the new "origs" file from above and you just do the delta processing one file at a time. I'm sure there's more to it than I'm imagining, but that general pattern I quickly described is HIGHLY leveraged by many Pig users out there. Good luck & thanks for accepting my answer! ...

Hi Kibrom Gebrehiwot, Unsure if you're still stuck here. What you can do is goto Manage Ambari > Versions > and update the HDP and HDP-UTILS URL's. You will be able to find your relevant URL's in your version document of ambari. Try to use the Public URL's if you have internet access. Thanks, Adnan Khan ... View more
