org.apache.ranger.plugin.client.HadoopException: Exception on REST call to KnoxUrl : https://xxx:8443/gateway/admin/api/v1/topologies..

resolved:

The ranger plug-in client does not need SSL handshake when calling knox, so it is replaced with apache http client to solve the SSL handshake problem and adjust the knox interface.
