Info
titleINFO

Datameer supports Tableau version 9 and 10 in the formats HYPER, TDE and TDSX. Older versions might not function work as expected and are not supported.

Using the HYPER format requires at minimum operating system CentOS 7 with libc6 version >2.15/ libstdc++6 version >6.1.0.
Local execution can be used but is not scaleable.

Info
titleINFO

MapR distributions currently don't support the export to a Tableau server in the TDE format. This is due to the maprfs-x.x.x-mapr.jar which can't be changed by Datameer.

    titleAs of Datameer v6.1

    An option allows you to designate the owner for a export file on the Tableau server. Choose between either the current Datameer owner of the connection or a specific owner on the Tableau server.

    If the user of the Datameer connection isn't a Tableau Server admin, you can only choose the owner of the connection. If the user is later set as a Tableau Server admin, the option to change to a different Tableau owner is possible.

    If the owner has been set to be a specific owner on the Tableau server and that owner is later deleted, the next time the export jobs runs, the radio button automatically reverts back to Use Owner from the Datameer connector on Tableau.
