For certain grant/revoke requests, we are using the full name, which is a fully 
qualified user principal.

@Override
  public void grantPrivilegeToUser(TCatalogServiceRequestHeader header,
      TGrantRevokePrivParams params, TDdlExecResponse response) throws 
ImpalaException {
    List<GrantRevokeRequest> requests = createGrantRevokeRequests(
====>        header.getRequesting_user(), true, params.getPrincipal_name(),
        Collections.emptyList(), plugin_.get().getClusterName(),
        header.getClient_ip(), params.getPrivileges());


@Override
  public void revokePrivilegeFromUser(TCatalogServiceRequestHeader header,
      TGrantRevokePrivParams params, TDdlExecResponse response) throws 
ImpalaException {
    List<GrantRevokeRequest> requests = createGrantRevokeRequests(
====>        header.getRequesting_user(), false, params.getPrincipal_name(),
        Collections.emptyList(), plugin_.get().getClusterName(),
        header.getClient_ip(), params.getPrivileges());

@Override
  public void grantPrivilegeToGroup(TCatalogServiceRequestHeader header,
      TGrantRevokePrivParams params, TDdlExecResponse response) throws 
ImpalaException {
    List<GrantRevokeRequest> requests = createGrantRevokeRequests(
=>>>        header.getRequesting_user(), true, null,
        Collections.singletonList(params.getPrincipal_name()),
        plugin_.get().getClusterName(), header.getClient_ip(), 
params.getPrivileges());

  @Override
  public void revokePrivilegeFromGroup(TCatalogServiceRequestHeader header,
      TGrantRevokePrivParams params, TDdlExecResponse response) throws 
ImpalaException {
    List<GrantRevokeRequest> requests = createGrantRevokeRequests(
===>        header.getRequesting_user(), false, null,
        Collections.singletonList(params.getPrincipal_name()),
        plugin_.get().getClusterName(), header.getClient_ip(), 
params.getPrivileges());

Ranger expects a short name instead. The bug existed since the original 
implementation [1], but the code has been later refactored.
