Subject Re: Pig view in kerberos cluster
Date Mon, 22 Feb 2016 14:11:20 GMT
Hi Margus

Can you check the following properties are present in custom webhcat-site section of hive
services in Ambari.

webhcat.proxyuser.<ambari server principal>.groups=*
webhcat.proxyuser.<ambari server principal>.hosts=*


http://docs.hortonworks.com/HDPDocuments/Ambari-2.2.0.0/bk_ambari_views_guide/content/_setup_WebHCat_proxy_user_pig_view.html


Thanks
Gaurav
