    Error when initializing worker node - appears to be trying to connect on port 8133?

    Technical Services

      This is on Windows Server 2016 on AWS. For the purposes of troubleshooting, I have the windows firewalls on both machines turned off, and the traffic between them wide open in the AWS security groups. All of the Tableau services appear to be running.

       

      I am trying to add a worker node to my primary. I provide it the boostrap.json file & after a minute or two, says that the node failed to start. In the control_tabadminagent_node2-0.log, I see

       

      ZKWorker-ScheduledTask-0 : INFO  com.tableausoftware.tabadmin.agent.zookeeper.ConnectionHolder - Closing Zookeeper client instance org.apache.curator.framework.imps.CuratorFrameworkImpl@25e07a61 in state LATENT.

      ZKWorker-ScheduledTask-0-SendThread(ffctableaua:8133) : INFO  org.apache.zookeeper.ClientCnxn - Opening socket connection to server ffctableaua/10.0.0.81:8133. Will not attempt to authenticate using SASL (unknown error)

      ZKWorker-ScheduledTask-0-SendThread(ffctableaua:8133) : WARN  org.apache.zookeeper.ClientCnxn - Session 0x0 for server null, unexpected error, closing socket connection and attempting reconnect

      java.net.ConnectException: Connection timed out: no further information

       

      Further down, I also see:

       

      ZKWorker-ScheduledTask-0-SendThread(ffctableaua:8133) : INFO  org.apache.zookeeper.ClientCnxn - Opening socket connection to server ffctableaua/10.0.0.81:8133. Will not attempt to authenticate using SASL (unknown error)

      main : INFO  com.tableausoftware.tabadmin.agent.zookeeper.ConnectionHolder - Closing Zookeeper client instance org.apache.curator.framework.imps.CuratorFrameworkImpl@4dcb91d6 in state STARTED.

      main : ERROR com.tableausoftware.commandline.SwitchCommand - Failed to execute command install

       

       

      It looks like it's trying to open a connecton to the primary node on port 8133, but nothing seems to be running on port 8133 -- I can telnet to the administration port, 8850, and port 80 for example, from the secondary to the primary, but not 8133. I cannot telnet to that port from the primary itself either.

       

      Is there anything I need to do/configure on the primary node prior to adding the secondary?

       

      Thank you in advance
