Hello, We have a solrCloud running solr 8.6.3 and we want to write our logs as jsons.
We looked around and decided that the best way to achieve this is by using the log4j-layout-template-json extension published by apache. (https://logging.apache.org/log4j/2.x/manual/json-template-layout.html) we tried to implement it by adding the jar to our lib folder (where we put the custom solr components we wrote) and using the configuration written for this purpose in solr's repo (https://github.com/apache/solr/blob/b0a4b0213016bef59fcc6a280c498cbf35e64230/solr/docker/tests/cases/test_log4j/log4j2.xml) but ended up disappointed because instead of writing the logs in json format we got a watered down version of our logs that is not a valid json. we did some digging an discovered that in solr 9.0.0 this jar was added to solr's build. however, we are unable to upgrade to solr 9 at the moment. is there a way to apply this jar to the cluster in solr 8.6.3?
