Description:
alter table does not autocommit rows.
This as ha_enable_transactions(FALSE) is called _after_ external_lock.

This make ndb fail big alter table's as MaxNoOfConcurrentOperations becomes a bottleneck.

How to repeat:
alter table

As a workaround one might:

set ndb_use_transactions=off;
alter ;
set ndb_use_transactions=on;
