Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

How to repeat:
1.Start cluster

2. Create log file group with small value of undo_buffer_size:
CREATE LOGFILE GROUP lg1 ADD UNDOFILE 'undofile.dat' INITIAL_SIZE 20M UN
DO_BUFFER_SIZE 1 ENGINE=NDB;

3. Create tablespace:
CREATE TABLESPACE ts1 ADD DATAFILE 'datafile.dat' USE LOGFILE GROUP lg1
INITIAL_SIZE 10M ENGINE=NDB;

4. Create a table
 CREATE TABLE t1 (a INT NOT NULL PRIMARY KEY, b VARCHAR(4000)) TABLESPACE
 ts1 STORAGE DISK ENGINE=NDB;

Suggested fix:
Seems error is correct but ndbd nodes died...

Are there any figures available as to define "small" ? 

As of which value could this problem dissappear ?

'Small' value means 64K or less
