Hi,
I have a Solr Cloud 7.2.1 setup and used SolrJ (7.2.1) to create 1000
collections with a few documents. During that I got multiple times in
the Solr logs exceptions because an access of the /get handler of a
collection failed. The call stack looks like this:

I did not define a /get request handler but I also don't see one being
default in the solrconfig.xml files that come with Solr 7.2.1. Do I need
to add that as described in
https://www.garysieling.com/blog/fixing-solrj-error-expected-mime-type-applicationoctet-stream-got-texthtml
or is there something wrong in Solr? Is Solr doing those /get calls? My
program is not doing any, unless SolrJ does them under the covers, and
is actually not showing any error.
regards,
Hendrik
