    Tableau authentication to Cloudera Hadoop fails to authentication LDAP username and password

    Deepak Murthy




      Tableau 8.1.4 32 bit

      Cloudera Hadoop - 32 bit


      When we configure DSN Setup from Cloudera using Hive server2 we can successfully login to Hadoop. (Note we are currently using LDAP authenticatio), we need to provide username and password field here.


      When we try to configure same thing in Tableau -> Connect to Data --> Cloudera Hadoop Hive Connection

      Although there is Server name, Type -> HiveServer2 and Authentication - does not have Username and password it only has Username

      On entering only username it fails to authenticate and we receive error in Hadoop cluster as below:

      Inorder for us to continue Tableau reporting using Hadoop, we need you to further fix this issue.


      We contacted Hadoop support team and they mentioned to contact Tableau to fix this issue on their end.


      Need your help further to fix this issue and provide us the fix.
