Description

Adding a new node involves invoking confd_client infra_instances_add command which internally invokes c4 to add the new node. However, if the installation had at least a single update in the past, c4 would fail to find the Exasol archive that is expected to be located in the home directory of the current node.

Workaround

c4 connect -i PLAY_ID -s host -n 11
VERSION=8.34.0
ALIAS=$(c4 config -e .play.working_copy)
mv $HOME/exasol-$VERSION.tar.gz $HOME/$ALIAS.tar.gz

Fix

c4 will now correctly identify the expected name of the archive, even if the deployment was updated in the past.
