[Nagiosplug-help] Nagios - MYSQL Cluster integration

Hi all,
We are setting up Nagios to store all its data into MYSQL Cluster
environment.  We modified all references of MYISAM engine to NDBCLUSTER
in the mysql.sql file that comes with the ndoutils-1.4b8 package.
After we ran the ./installdb script, it created some tables but not all
and generated this error message:
ERROR 1118 (42000) at line 412: Row size too large. The maximum row size
for the used table type, not counting BLOBs, is 8052. You have to change
some columns to TEXT or BLOBs
According to the MySQL docs, there are two differences between varchar
and text (besides how the data is stored)-
-	For indexes on TEXT columns, you must specify an index prefix
length. For CHAR and VARCHAR, a prefix length is optional. 
-	TEXT columns cannot have DEFAULT values.
			
My first question, is Nagios supported on MYSQL Cluster?  If so, using
the default value of NULL is problematic for those columns?
We also tired populating the tables manually, but it's killing the NDB
processes.
ANY ADVISE?  

Thank you,
Tony K
