The hive.server2.proxy.use option allows a user to run queries under their Zeppelin session user ID. If you need to restrict access to a table, you can specify this value to prevent users from making changes. Alternatively, you can use a custom value in the Hive.server2.proxy.user variable. However, you should be aware that this feature is not supported by all Hive servers. If you want to use it, you should follow the documentation provided by the HiveServer2 project.

To configure the Hive service, go to Cloudera Manager and select Configuration, Category, and Security. In the right panel, choose “Services” and “Configuration” and “Trust Store.” In the ‘Authentication’ section, select ‘HiveServer2’. In the ‘Authentication Provider’ section, click on ‘Pluggable authentication’ and specify the authentication provider.

Once you have enabled the HiveServer2 proxy, you can run jobs and execute queries as the connected user. This bypasses the Sentry authorization process, which will prevent unauthorized users from accessing sensitive or restricted data. Once the cluster is secure, you can run multiple copies of Hive as the same user. To enable HiveServer2, you must first enable Sentry in your local machine.

The hive.server2 user should be set to an authenticated user. You must grant the HiveServer2 service execution permissions to the impersonated user. This is the default action for a’service principal’. If you have more than one Hive server, make sure that each server is running under a different host. If the cluster is secure, you must disable the proxy to avoid a connection failure.

Using HiveServer2 with Kerberos authentication is possible. LDAP uses the same credentials as the Hive API. The LDAP user must be set up with the corresponding permissions. Its privileges should be configured accordingly. Ensure that you have sufficient resources on the server. If your cluster is secure, then the user must have a valid username and password. This setting should be done by the same person as the hive server.

After installing the Hive.Server2 service, you must configure the Kerberos authentication service. The process of implementing this feature is described in detail below. In addition to Kerberos, the KNIME Server uses a keytab file to allow the user to access data. If the hive.server2.proxy.USER parameter is used in the context of a Hive server, the user can create a db.database using a database.

The Hive.server2 proxy user is the user that authenticates the users for the Hive platform. The default hive.server2 port is The user must have execute permissions in order to use this. When the password is incorrect, it will not connect to the cluster. When this happens, the user will be denied access to the database. This can lead to serious security issues.

After setting up the HiveServer2 proxy, you must configure the user’s user name. By default, HiveServer2 allows users to login only to their domain, so it’s crucial to use the full name when connecting to other services. By doing so, you can enable the centralized security service to prevent the wrong user from accessing data. This service provides the most secure cluster for data processing.

The HiveServer2 proxy must be installed on the cluster and configured properly. If you have an existing Hive service, you can use it without registering it. By default, Hive uses the default server details. Pluggable authentication is a powerful tool for Hive. Once configured, it can be accessed by multiple users. The underlying database is not encrypted, but it’s still protected.

To enable the hive.server2.proxy.use.user_preferred_id is required when using the hive.server2.proxy_user.user option does not allow user impersonation. It is required for HiveServer2 if the parameter is enabled. The password must be set as an optional parameter. Otherwise, you should enable the hive.server2.proxies.use flag.

LDAP support for HiveServer2 is an added benefit. LDAP is an open source database, and most implementations support LDAP for username and password authentication. To connect to LDAP, enter the LDAP user’s username and password. The LDAP provider will validate the credentials. If the hive server does not support LDAP, use a TLS/SSL VPN.
