Shouldn't the entries

  { 630, HA_ERR_FOUND_DUPP_KEY, 0 },
  { 893, HA_ERR_FOUND_DUPP_KEY, 0 },

in the 5.0 sql/ha_ndbcluster.cc error code mapping
array have their show_warnings flag set, too,
like the other cases of multiple ndb errors mapping 
to the same handler error? So that one can use
SHOW WARNINGS on receiving such an error to check
what really happened (630 or 893)?

In 5.1 we have the same problem, although implemented
in a different way, here the HA_ERR_FOUND_DUPP_KEY
case should be removed from the 

    return error;

in the ndb_to_mysql_error() function in ha_ndbcluster.cc?

How to repeat:
see the code snippets above

Suggested fix:
make HA_ERR_FOUND_DUPP_KEY error cases throw warning like the other ambiguous engine error codes that may be caused by multiple cluster error codes
