The Splunk deployer sends apps to the search head cluster members by default to the path etc/shcluster/< app-name>/default. The deployer is a Splunk component that distributes apps and configurations to members of a search head cluster.
Splunk's documentation recommends placing the configuration bundle in the
$SPLUNK_HOME/etc/shcluster/apps directory on the deployer, which then gets distributed to the search head cluster members. However, it should be noted that within each app's directory, configurations can be under default or local subdirectories, with local taking precedence over default for configurations. The reference to etc/shcluster/<app-name>/default is not a standard directory structure and might be a misunderstanding. The correct path where the deployer pushes configuration bundles is
$SPLUNK_HOME/etc/shcluster/apps
