How to repeat:
master> create table t1(c1 int, c2 int, c3 int);
Query OK, 0 rows affected (0.69 sec)

master> insert into t1 values (1,1,1);
Query OK, 1 row affected (0.04 sec)

master> insert into t1 values (1,1,1);
Query OK, 1 row affected (0.01 sec)

master> create index t1_i on t1(c2,c3);
Query OK, 0 rows affected (0.92 sec)
Records: 0  Duplicates: 0  Warnings: 0

master> create unique index t1_i2 on t1(c2);
ERROR 1296 (HY000): Got error 4009 'Cluster Failure' from NDBCLUSTER
master> 

this produces a hang:

master> create table t1(c1 int, c2 int, c3 int);
Query OK, 0 rows affected (0.67 sec)

master> insert into t1 values (1,1,1);
Query OK, 1 row affected (0.04 sec)

master> create unique index t1_i2 on t1(c2);
.... hangs... very lkong time out
ERROR 1297 (HY000): Got temporary error 4025 'Node failure caused abort of transaction' from NDBCLUSTER
