Delete/remove Solr configuration from ZooKeeper using zkcli?

From within your zookeeper bin directory, start zkCli.sh, this will open zookeeper console.

Then fire the following command to delete a node/config:

rmr /configs

You missed the -z parameter which is mandatory (Zookeeper-3.4.8).

The correct command for deleting configset AAA on Solr (v.6.1.0) running on localhost with zookeeper on port 2181 is:

./server/scripts/cloud-scripts/zkcli.sh -cmd clear -z "localhost:2181" /configs/AAA

when in the root directory of Solr.

So to answer your question: Yes, you can use clear, and the path should be /configs/< name of configset >
