Get list of collection

Hi All,

I have a requirement to get the list of *collection* available in Solr. we
are using solrj library.

I am able to fetch the list of cores but not getting ways to fetch the list
of collections.

Below is the sample example, that i am using to fetch the cores:

        CoreAdminRequest request = new CoreAdminRequest();
        request.setAction(CoreAdminAction.STATUS);
        CoreAdminResponse cores = request.process(server);

        // List of the cores
        List<String> coreList = new ArrayList<String>();
        for (int i = 0; i < cores.getCoreStatus().size(); i++) {
            coreList.add(cores.getCoreStatus().getName(i));
        }

Please help.

That method is private, so you can't use it in a user program.  I think
this would probably do what you want, if server is an instance of
CloudSolrServer:

Set<String> list =
server.getZkStateReader().getClusterState().getCollections();

Thanks,
Shawn

Hi Erick,

We are using the 4.7.2 version of solr and no getCollectionList() method is
present in CloudSolrServer class.

I think you want CloudSolrServer.getCollectionList()
