Hi,

The cluster is not kerberised but installed ranger and atlas. As we are not having plan of search in atlas, we haven't installed solr. Atlas UI is not accessible in our cluster. We could found the following errors in application log:

Does this mean that I solr CLI is not working or has to something with solr.
