"No spec file" errors when trying to deploy Splunk Add-on for VMware from the index master node

[keio_splunk]

VMware data collection is working fine but when pushing out Splunk Add-on for VMware from the index master node the following warnings are reported:
[Not Critical]No spec file for: /app/splunk/etc/master-apps/Splunk_TA_esxilogs/default/eventgen.conf
[Not Critical]No spec file for: /app/splunk/etc/master-apps/Splunk_TA_vcenter/default/eventgen.conf

splunkd.log:
WARN CMBundleMgr - Bundle validation warnings bundle=/app/splunk/var/run/splunk/cluster/remote-bundle/2ea968f32581661ba4910e8e0322176f-1542938006.bundle, err=[Not Critical]No spec file for: /app/splunk/etc/master-apps/Splunk_TA_esxilogs/default/eventgen.conf\n;[Not Critical]No spec file for: /app/splunk/etc/master-apps/Splunk_TA_vcenter/default/eventgen.conf\n

Why are the warnings generated?

[keio_splunk · Accepted solution]

The warnings thrown by the cluster master is expected behavior and can be safely ignored.
The eventgen.conf in Splunk_TA_esxilogs and Splunk_TA_vcenter are used for generating dummy data along with SA-Eventgen which will provide the spec file(eventgen.conf.spec).
