"C6" is CDH version 6?   Each ODBC document (pdf) states that the driver supports 5.x. Is 6.x also supported? Or is it not supported but at a level that works for compatibility?   I refer below:  * Hive ODBC doc   * 2.5.25 : https://www.cloudera.com/documentation/other/connectors/hive-odbc/2-5-25/Cloudera-ODBC-Driver-for-Apache-Hive-Install-Guide.pdf    * The Cloudera ODBC Driver for Apache Hive supports Apache Hive versions 0.11 through 2.1, and CDH versions 5.0 through 5.13. The driver also supports later minor versions of CDH 5.    * Impala ODBC doc   * 2.5.42 : https://www.cloudera.com/documentation/other/connectors/impala-odbc/2-5-42/Cloudera-ODBC-Driver-for-Impala-Install-Guide.pdf    * The Cloudera ODBC Driver for Impala is recommended for Impala versions 1.0.1 through 2.10, and CDH versions 5.0 through 5.13. The driver also supports later minor versions of CDH 5.   ... View more

Thank you for your quick reply.   In the Kerberized environment, when LB was set for HS2 and Impalad, I understood that I can connect directly to HS2, but I can not connect directly to Impalad.   Thank you for responding to DOC correction. Because I often refer to DOC, I help a lot. ... View more

Thank you for your reply.   I understood about support for only one LB setting.   Please make sure that you can connect directly to HS2.   The following description in the procedure states that in a Kerberized CDH cluster, direct connection to HS2 fails, but is it possible to connect? In the case of impalad, can you connect without using impala-shell? Can ODBC / JDBC and other connections be possible?  * https://www.cloudera.com/documentation/enterprise/6/6.0/topics/admin_ha_hiveserver2.html#concept_c1m_3td_wv   * ・Warning:    * ・On Kerberos-enabled clusters, you must use the load balancer for all connections. After you enable HiveServer2 high availability, direct connections to HiveServer2 instances fail.  * https://www.cloudera.com/documentation/enterprise/6/6.0/topics/impala_proxy.html#proxy_kerberos   * Once you enable a proxy server in a Kerberized cluster, users will not be able to connect to individual impala daemons directly from impala-shell. ...

thank you for your answer. I understood that the Catalog Server requires a CPU as well as Impalad. ... View more
