Issue

When installing or restarting Tableau Server, starting up fails (despite several retries) and the following error might occur in the TSM Status: 

"Tableau Server Tableau Prep Conductor [...] is in an error state."

Environment

  • Tableau Server 2019.2
  • Data Preparation License is Used

Resolution

Option 1

Upgrade to Tableau Server 2019.3 or a newer version. See Tableau Server Downloads and Release Notes for downloads of current and previous versions of Tableau Server. For more information on current releases, see Upgrade Tableau Server and Server Upgrade.

Option 2

Single node:
As a Tableau Server Administrator, follow the steps below: 
  1. Open up Task Manager
  2. End-Task for run-flowprocessor.exe
Multi-node:
As a Tableau Server Administrator, follow the steps below: 
  1. Go to TSM Topology Page
  2. Remove Backgrounder from the node
  3. Pending-Changes Apply
  4. Re-add Backgrounder to the node
  5. Pending-Changes Apply

Since Flow Processor / Conductor is coupled with Backgrounder, the process needs to be removed and re-added for the process start up call

Cause

Hyper does not start up in time while the Flow Processor tries to start up. Additionally, this behavior was related to a known issue (ID: 922917) and it has been fixed in Tableau Server 2019.3 and later versions.
