Configure HiveServer 2 Clients to use Kerberos

When HiveServer 2 is configured to use Kerberos authentication, you must also configure HiveServer2 clients to use Kerberos.

On each node where HiveServer2 clients (not including Beeline) are installed, reconfigure the following option in env.sh (/opt/mapr/conf/env.sh) file:

Existing Configuration	Required Configuration
`MAPR_HIVE_LOGIN_OPTS="-Dhadoop.login=maprsasl"`	`MAPR_HIVE_LOGIN_OPTS="-Dhadoop.login=hybrid"`

Note: This configuration is listed in the portion of the file that begins with if [ "$MAPR_SECURITY_STATUS" = "true" ];. However, you should make the change in the /opt/mapr/conf/env_override.sh file. For more information, see About env_override.sh.

On each node where Beeline is installed, reconfigure the following option in beeline.sh ($hive_home/bin/ext/beeline.sh) file:

Existing Configuration	Required Configuration
`HADOOP_OPTS="$HADOOP_OPTS"`	`HADOOP_OPTS="$HADOOP_OPTS"`

For more information, see Connecting to Hive.

Note: The MAPR_HIVE_LOGIN_OPTS and MAPR_HIVE_SERVER_LOGIN_OPTS were added in 1504 release of Hive 0.13 and Hive 1.0. If you have Hive 0.13 from a prior release, you do not need to configure these properties. Instead, set MAPR_ECOSYSTEM_LOGIN_OPTS and MAPR_ECOSYSTEM_SERVER_LOGIN_OPTS to "-Dhadoop.login=hybrid" in /opt/mapr/conf/env.sh.
