> [HBASE-22377|https://issues.apache.org/jira/browse/HBASE-22377] will 
> introduce a new API that does not require ADMIN permissions to check the 
> existence of a namespace.
> Currently, CQSI#ensureNamespaceCreated calls 
> HBaseAdmin#getNamespaceDescriptor which eventually on the server causes a 
> call to AccessController#preGetNamespaceDescriptor. This tries to acquire 
> ADMIN permissions on the namespace. We should ideally use the new API 
> provided by HBASE-22377 which does not require the phoenix client to get 
> ADMIN permissions on the namespace. We should acquire ADMIN permissions only 
> in case we need to create the namespace if it doesn't already exist.
> Similarly, CQSI#ensureTableCreated should first check the existence of a 
> table before trying to do HBaseAdmin#getTableDescriptor since this requires 
> CREATE and ADMIN permissions.
