Description:
I have created cluster environment on 4 pc

>> For disk space storage i have created log group and tablespace like

>> NOW I have created 1 database on cluster named db_1. It has just 1 table

>> in this output we can see that text field is stored in memory
How to repeat:
whenever any on make table on cluster 5.1.14 and give text datatype in anyfield.
then after just check
ndb_desc -c localhost temp_1 -d db_1 –p
u got follwing output
[root@rhel4mysql2 mysql-cluster]# ndb_desc -c localhost temp_1 -d db_1 –p
