Noble Paul commented on SOLR-6787:
----------------------------------
If you have a Request Handler configured in {{solrconfig.xml}} you can't delete
it using the config API. However, you can just override it by registering a
{{NotFoundRequestHandler}} with the same name using the config API
> API to manage blobs in Solr

> A special collection called .system needs to be created by the user to
> store/manage blobs. The schema/solrconfig of that collection need to be
> automatically supplied by the system so that there are no errors
> APIs need to be created to manage the content of that collection
> {code}
> #create your .system collection first
> http://localhost:8983/solr/admin/collections?action=CREATE&name=.system&replicationFactor=2
> #The config for this collection is automatically created . numShards for this
> collection is hardcoded to 1
> #create a new jar or add a new version of a jar
> curl -X POST -H 'Content-Type: application/octet-stream' --data-binary
> @mycomponent.jar http://localhost:8983/solr/.system/blob/mycomponent
> # GET on the end point would give a list of jars and other details
> curl http://localhost:8983/solr/.system/blob
> # GET on the end point with jar name would give details of various versions
> of the available jars
> curl http://localhost:8983/solr/.system/blob/mycomponent
> # GET on the end point with jar name and version with a wt=filestream to get
> the actual file
> curl http://localhost:8983/solr/.system/blob/mycomponent/1?wt=filestream >
> mycomponent.1.jar
> # GET on the end point with jar name and wt=filestream to get the latest
> version of the file
> curl http://localhost:8983/solr/.system/blob/mycomponent?wt=filestream >
> mycomponent.jar
> {code}
> Please note that the jars are never deleted. a new version is added to the
> system everytime a new jar is posted for the name. You must use the standard
> delete commands to delete the old entries
