I'm attempting to use the following http request to create a solr core:
http://localhost:8983/solr/admin/cores?action=CREATE&name=service_name.resource&generateResources=false
The response i'm getting is
[create] action is not supported!
I'm using the version of dse 6 available direct from the site. 5.0 and 5.1 work fine, but 6 returns the above error, any ideas?
Many of the HTTP APIs supported in the 5.x versions are removed in the DSE 6, including the core administration.
You need to use CQL syntax (recommended), or dsetool (older, less recommended) to manipulate the DSE Search cores.
P.S. From my experience, using the CQL it is easier, and doesn't require to have access to Solr UI, or command line.
