Description

Exasol “As-App” installation would fail if the user configured to run Exasol via CCC_HOST_IMAGE_USER is not a member of a group with the same name.

e.g. if CCC_HOST_IMAGE_USER=exasol, installation would fail if the exasol user was not also a member of the exasol group.

The “rootless” deployment was not affected.

Workaround

Create a group with the same name as the user configured to run Exasol.

Fix

Installation works regardless of group membership of the user.
