Descrizione

Issue

When attempting to connect to a Cloudera Hadoop Hive data source from  Tableau Server installed on Linux OS, the following error occurs:

 

The drivers necessary to connect to this database server are not properly installed.

 

Cause

The permission was lacking for the driver configuration files.

 

Risoluzione

Ensure the correct Cloudera Hadoop Hive driver is installed on the Tableau Server machine and ODBC driver configuration is complete. 

 

  1. Download the correct drivers for Tableau, see Drivers & Activation. 
  2. Verify the permissions of the following two configuration files.
       
    • /etc/odbcinst.ini
    • /opt/cloudera/hiveodbc/lib/64/cloudera.hiveodbc.ini
  • If the permissions are not 777 for both files, apply 777 permission to both configuration files by executing the following commands:
     
    • sudo chmod -R 777 /etc/odbcinst.ini
    • sudo chmod -R 777 /opt/cloudera/hiveodbc/lib/64/cloudera.hiveodbc.ini
