Apache Hive RBAC Configuration with SQL
Introduction
This guide addresses common Apache Hive Role-Based Access Control (RBAC) configuration with SQL issues, specifically focusing on the challenges encountered when setting up admin roles and permissions with SQL queries. We'll walk through a real-world example of troubleshooting and resolving these issues in a Docker-based Hive environment.
Understanding the Problem
Common Error Messages
When attempting to configure RBAC in Hive with queries like:
SHOW ROLES;
SET ROLE admin;
CREATE ROLE test_role;
GRANT ROLE test_role TO USER tester;
For example, for role creation query you might encounter various error messages depending on your connection method:
JDBC Connection (e.g., DBeaver)
SQL Error [1] [08S01]: org.apache.hive.service.cli.HiveSQLException: Error while processing statement:
FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask.
Current user : root is not allowed to add roles. User has to belong to ADMIN role and have it as current role, for this action.
Hive CLI (e.g. beeline or hive -e)
FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask.
Failed to retrieve roles for null: Required field 'principal_name' is unset!
Struct:GetRoleGrantsForPrincipalRequest(principal_name:null, principal_type:USER)
Root Causes
The issues typically stem from:
- Incomplete authentication configuration
- Incorrect authorization provider settings
- Missing user-to-role mappings
- Improper service account permissions
Environment Setup for Apache Hive RBAC Configuration with SQL
Prerequisites
Before proceeding, ensure you have:
- Administrative access to your Hive environment
- Ability to modify Hive configuration files
- Access to restart Hive services
- Basic understanding of XML configuration files
Locating Configuration Files
First, locate your Hive configuration file hive-site.xml
directory. You can run these commands to check the common locations:
ls /etc/hive/conf/hive-site.xml
ls /etc/hadoop/conf/hive-site.xml
ls /usr/lib/hive/conf/hive-site.xml
ls /opt/hive/conf/hive-site.xml
ls $HIVE_HOME/conf/hive-site.xml
Or run this command to find the correct location:
find / -name "hive-site.xml" 2>/dev/null
File Permission Requirements
Ensure proper file permissions:
ls -l /opt/hive/conf/hive-site.xml
# Should show something like:
# -rw-r--r-- 1 root root 3342 Jan 31 16:04 /opt/hive/conf/hive-site.xml
Step-by-Step Solution for Apache Hive RBAC Configuration with SQL
1. Backup Existing Configuration
Always create a backup before making changes:
cp /opt/hive/conf/hive-site.xml /opt/hive/conf/hive-site.xml.backup
2. Update hive-site.xml
Create a new configuration file with all necessary settings:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<!-- Metastore Connection -->
<property>
<name>hive.metastore.uris</name>
<value>thrift://hive-metastore:9083</value>
</property>
<!-- Database Configuration -->
<property>
<name>datanucleus.autoCreateSchema</name>
<value>false</value>
</property>
<property>
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:postgresql://hive-metastore-postgresql/metastore</value>
</property>
<property>
<name>javax.jdo.option.ConnectionDriverName</name>
<value>org.postgresql.Driver</value>
</property>
<property>
<name>javax.jdo.option.ConnectionPassword</name>
<value>hive</value>
</property>
<property>
<name>javax.jdo.option.ConnectionUserName</name>
<value>hive</value>
</property>
<!-- Authentication & Authorization Configuration -->
<property>
<name>hive.security.authorization.enabled</name>
<value>true</value>
</property>
<property>
<name>hive.server2.enable.doAs</name>
<value>false</value>
</property>
<property>
<name>hive.users.in.admin.role</name>
<value>root</value>
</property>
<property>
<name>hive.server2.authentication</name>
<value>NONE</value>
</property>
<property>
<name>hive.security.authorization.manager</name>
<value>org.apache.hadoop.hive.ql.security.authorization.StorageBasedAuthorizationProvider</value>
</property>
<property>
<name>hive.metastore.pre.event.listeners</name>
<value>org.apache.hadoop.hive.ql.security.authorization.AuthorizationPreEventListener</value>
</property>
<property>
<name>hive.security.metastore.authorization.manager</name>
<value>org.apache.hadoop.hive.ql.security.authorization.StorageBasedAuthorizationProvider</value>
</property>
<property>
<name>hive.security.authenticator.manager</name>
<value>org.apache.hadoop.hive.ql.security.HadoopDefaultAuthenticator</value>
</property>
<property>
<name>hive.metastore.execute.setugi</name>
<value>true</value>
</property>
</configuration>
3. Restart HiveServer2
# Find hiveserver2 location
which hiveserver2
# Stop the service
hiveserver2 stop
# Wait for complete shutdown
sleep 5
# Start the service
hiveserver2 start
# Wait for startup
sleep 10
Testing and Verification for Apache Hive RBAC Configuration with SQL
1. Verify Service Status
ps aux | grep hiveserver2
netstat -tulpn | grep 10000
2. Test RBAC Configuration
Using DBeaver or another JDBC client/connection:
SHOW ROLES;
SET ROLE admin;
CREATE ROLE user_role;
GRANT ROLE test_role TO USER tester;
Using hive -e/beeline:
Apache Hive RBAC Configuration with SQL Troubleshooting
Common Issues and Solutions
1. Principal Name Null Error If you see:
Required field 'principal_name' is unset!
Solution: Verify the hive.security.authenticator.manager
setting is correct and HiveServer2 has been restarted.
2. User Not in Admin Role If you see:
root doesn't belong to role admin
Solution: Check the hive.users.in.admin.role
property and ensure it contains your username.
3. Configuration Not Taking Effect
Solution:
- Verify file permissions
- Confirm HiveServer2 restart
- Check logs for startup errors
Advanced Configuration for Apache Hive RBAC
Custom Authentication Providers
For environments requiring custom authentication:
<property>
<name>hive.security.authenticator.manager</name>
<value>com.your.custom.AuthenticatorManager</value>
</property>
Multiple Admin Users
To configure multiple admin users:
<property>
<name>hive.users.in.admin.role</name>
<value>root,admin1,admin2</value>
</property>
Further Considerations
Security Best Practices
- Regularly rotate passwords
- Implement proper audit logging
- Use SSL/TLS for connections
Performance Impact
- Monitor query performance after enabling RBAC
- Adjust memory settings if needed
Maintenance
- Regular backup of configuration files
- Document all custom settings
- Maintain user-role mapping documentation
