> The secure metastore always doesn't allow any client to connect without a valid kerberos ticket. Also the client requests are executed by impersonating the requesting userid. If metastore principal doesn't have privileges to impersonate the connecting user, then the DDL operations (eg create table, partition etc) will fail. However any user with valid Kerberos ticket is can connect to metastore service and perform read-only metadata operations. For example, get list of databases, tables; properties of each table like HDFS location, file type etc.
> The secure metastore behavior should be consistent. If a the metastore server doesn't have privileges to impersonate the connecting user, then it should reject connection.
