    Tableau Server Cluster -  Worker initialization failed

    Manolis Vrailas

      We are trying to set up a Tableau Cluster with Amazon EC2 instances. We configure VPC security groups , we temporarily turn of Windows Firewall to allow communication along servers.
      Then stopped the primary Server ( where Tableau server is ), at the configuration menu we added the first worker and save.
      The procedure of seting up the worker started and fails at  "Restarting Worker"
      Gather some information from tabadmin.log we can see the below :

      Both Tableau Server and Worker are 10.1.1

       

      Any thoughts ?
