Description

Stock techproduct example. Calling http://localhost:8983/solr/techproducts/config/overlay returns

{
  "responseHeader":{
    "status":0,
    "QTime":4},
  "overlay":{"znodeVersion":-1}}

This *znodeVersion* is phantom for several reasons:

1. There is no configoverlay.json file on the filesystem where all overlay properties are supposed to be stored
2. The overall config endpoint does not include this property even though it is supposed to be the superset of properties
3. What is this parameter doing in the non-cloud installation?
