Test the Hive Connection

Test the Hive Connection

After you configure users for MapR Ticket or Kerberos authentication on MapR clusters, you can test the Hive connection.
To test the Hive connection, or perform a metadata fetch task, use the following format for the connection string if the cluster is Kerberos-enabled:
jdbc:hive2://<hostname>:10000/default;principal=<SPN>
For example,
jdbc:hive2://myServer2:10000/default;principal=mapr/myServer2@clustername
When the mapping performs a metadata fetch of a complex file object, the user whose maprticket is present at %TEMP% on the Windows machine must have read permission on the HDFS directory to list the files inside it and perform the import action. The metadata fetch operation ignores privileges of the user who is listed in the HDFS connection definition.
