Configure Hive Metastore Clients to use Kerberos when Authenticating with Hive Metastore

Complete the following steps on each node where a Hive Metastore client is installed:

  1. Configure MAPR_HIVE_LOGIN _OPTS to" -Dhadoop.login=hybrid" in /opt/mapr/conf/ file.
  2. Configure the following property in hive-site.xml:
    Property Value
    hive.metastore.kerberos.principal <The HiveMetastore principal. For example, mapr/<FQDN@REALM>.>
      <description>The service principal for the metastore thrift server. The special string _HOST will be replaced automatically with the correct hostname.</description>
See Connecting to Hive for details on how to connect to HiveMetastore once the server and client node are configured to use Kerberos.
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/
