> Every time we access a sensitive property or iterate over a configuration when there is a CredentialProvider configured, it results in NN operations (as evidenced by FSNamesystem.audit logs).  I think that we could assume the CredentialProvider is static, read its properties once and cache them in memory to avoid these unnecessary reads.
