> 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.
