Bugs Fixed
* Restoration of metadata with ndb_restore -m occasionally
failed with the error message Failed to create index...
when creating a unique index. While diagnosing this
problem, it was found that the internal error
PREPARE_SEIZE_ERROR (a temporary error) was reported as
an unknown error. Now in such cases, ndb_restore retries
the creation of the unique index, and PREPARE_SEIZE_ERROR
is reported as NDB Error 748 Busy during read of event
table. (Bug #21178339)
