We have a connection to Impala working via ODBC using the Delegation UID parameter. We have configured our service account with a Kerberos ticket to be able to impersonate any user by following these instructions:
The Hive ODBC driver has the same Delegation UID parameter but I can't find any documentation on how to configure the users allowed to impersonate other users on Hive Server 2. How do we configure Hive Server 2 to allow a specific authenticated user to impersonate any user?
I think what you search is a configuration located inside the "core-site.xml" file (in HDFS configuration).
search for "proxyuser" on the documentation of Cloudera.
