Description:
Note; split of bug#27757

For DD scan, the data will not have been written to disk.
   This seems very hard to fix.
   Short term solution is to disable disk-scan

---

I disable diskscan to fix this problem.

How to repeat:
create table t1 (a int primary key, b int not null) storage disk engine = ndb;
begin;
insert into t1 values (1,1);
select * from t1;

this is not doable from ndbapi/mysqld
