  • cookieAuth is set to default as true 
  • cookieName : If any of the incoming cookies' key matches the value of cookieName, the JDBC driver will not send any login credentials/kerberos ticket to the server. i.e. the client will just send the cookie alone back to the server for authentication purpose. The default value of cookieName is hive.server2.auth (this is the HiveServer2 cookie name). 
  • To turn off cookie replay, cookieAuth=false must be used in the JDBC url.
  • Important Note : As part of HIVE-9709, we upgraded Apache http-client and http-core components of Hive to 4.4. To avoid any collision between this upgraded version of HttpComponents and other any versions that might be present in your system (such as the one provided by Apache Hadoop 2.6 which uses http-client and http-core components version of 4.2.5), the client is expected to set HADOOP_USER_CLASSPATH_FIRST=true before using hive-jdbc. Infact, in bin/beeline.sh we do this!

Connection URL When SSL Is Enabled in HiveServer2

...

In HTTP mode:  jdbc:hive2://<host>:<port>/<db>;ssl=true;sslTrustStore=<trust_store_path>;trustStorePassword=<trust_store_password>?hive.server2.transport.mode=http;hive.server2.thrift.http.path=<http_endpoint>.

Using 2-way SSL in HTTP Mode

HIVE-10447 enabled JDBC driver to support for 2-way SSL in HTTP mode. Please note that HiveServer2 currently does not support 2-way SSL. So this feature is handy when there is an intermediate server such as Knox which requires client to support 2-way SSL.

JDBC connection URL: jdbc:hive2://<host>:<port>/<db>;ssl=true;twoWay=true;sslTrustStore=<trust_store_path>;trustStorePassword=<trust_store_password>;sslKeyStore=<key_store_path>;keyStorePassword=<key_store_password>?hive.server2.transport.mode=http;hive.server2.thrift.http.path=<http_endpoint>.

 

  • <trust_store_path> is the path where client's truststore file lives. This is a mandatory non-empty field
  • <trust_store_password> is the password to access the truststore.
  • <key_store_path> is the path where client's keystore file lives. This is a mandatory non-empty field.
  • <key_store_password> is the password to access the keystore.

Using JDBC

You can use JDBC to access data stored in a relational database or other tabular format.
