Exported Site Fails from Distributed Install When no Data Engine is Present on the Primary Server

Issue

When exporting a site from a distributed Hyper-enabled Tableau Server for Windows installation that does not have a hosted Hyper/Data Engine instance on the Primary host machine, the following error might occur:

"Couldn't export <workbook/datasource>_reduced item for id <ID>"

Environment

Tableau Server 10.5 (and later versions) and 2018 (and later versions) for Windows
Windows Server

Resolution

Option 1

As a Tableau Server Administrator, upgrade to Tableau Server . For more information, see Upgrading Tableau Server in Tableau Help.

Option 2 (Workaround)

As an Administrator, manually start a Hyper instance on the primary computer:

Open an Administrative command prompt and run this command against the Tableau Server installation directory's "hyper" subfolder.
- For example for 10.5: "D:\Program Files\Tableau\Tableau Server\10.5\hyper\hyperd.exe" --no-password --config "D:\Program Files\Tableau\Tableau Server\data\tabsvc\config\hyper\hyper_standalone.yml" run
Leave the command prompt window with the aforementioned command running.
Perform the site export as normal.
When finished, press ctrl-c in the window running the script or close the command window.
