To setup a WebHCat
proxy user for the Ambari Server daemon account, you need to configure the proxy user in the
WebHCat configuration.
This configuration is determined by the account name the ambari -server daemon is running
as. For example, if your ambari -server is running as root, you set up an WebHCat proxy
user for root.
-
In Ambari Web, browse to .
-
On the Advanced tab, navigate to the Custom
webhcat-site section.
-
Click Add Property… to add the following custom
properties:
-
Save the configuration change and restart the required components as indicated
by Ambari.
webhcat.proxyuser.root.groups=*
webhcat.proxyuser.root.hosts=*
Notice the ambari-server daemon account name root is part of the property
name. Be sure to modify this property name for the account name you are running
the ambari-server as. For example, if you were running ambari-server daemon
under an account name of ambariusr, you would use the following properties
instead:
webhcat.proxyuser.ambariusr.groups=*
webhcat.proxyuser.ambariusr.hosts=*
Similarly, if you have configured Ambari Server for Kerberos, be sure to
modify this property name for the primary Kerberos principal user. For example,
if ambari-server is setup for Kerberos using principal
ambari-server@EXAMPLE.COM, you would use the following properties
instead:
webhcat.proxyuser.ambari-server.groups=*
webhcat.proxyuser.ambari-server.hosts=*
