When hive.server2.transport.mode is binary and hive.server2.authentication is KERBEROS, SSL encryption does did not currently work until Hive 2.0. Set hive.server2.thrift.sasl.qop to auth-conf to enable encryption. See HIVE-14019 for details. |

- Create the self signed certificate and add it to a keystore file using: keytool -genkey -alias example.com -keyalg RSA -keystore keystore.jks -keysize 2048 Ensure the name used in the self signed certificate matches the hostname where HiveServer2 will run.
List the keystore entries to verify that the certificate was added. Note that a keystore can contain multiple such certificates: keytool -list -keystore keystore.jks
Export this certificate from keystore.jks to a certificate file: keytool -export -alias example.com -file example.com.crt -keystore keystore.jks
Add this certificate to the client's truststore to establish trust: keytool -import -trustcacerts -alias example.com -file example.com.crt -keystore truststore.jks
Verify that the certificate exists in truststore.jks: keytool -list -keystore truststore.jks
Then start HiveServer2, and try to connect with beeline using: jdbc:hive2://<host>:<port>/<database>;ssl=true;sslTrustStore=<path-to-truststore>;trustStorePassword=<truststore-password>

HiveServer2 job credential provider
Starting Hive 2.2.0 onwards (see HIVE-14822) Hiveserver2 supports job specific hadoop credential provider for MR and Spark jobs. When using encrypted passwords via the Hadoop Credential Provider, HiveServer2 needs to forward enough information to the job configuration so that jobs launched across cluster can read those secrets. Additionally, HiveServer2 may have secrets that the job should not have such as the Hive Metastore database password. If your job needs to access such secrets, like S3 credentials, then you can configure them using the configuration steps below:
...
A Web User Interface (UI) for HiveServer2 provides configuration, logging, metrics and active session information. The Web UI is available at port 10002 (127.0.0.1:10002) by default.
- Configuration properties for the Web UI can be customized in hive-site.xml, including hive.server2.webui.host, hive.server2.webui.port, hive.server2.webui.max.threads, and others.
- Hive Metrics can

- by viewed by using the "Metrics Dump" tab.
- Logs can be viewed by using the "Local logs" tab.
The interface is currently under development with HIVE-12338.
