HIVE-9709 introduced support to JDBC driver to enable cookie replay. This is turned to on by default so that incoming cookies can be sent send back to the server for authentication purpose.
...
- 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 with 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!
