Warning : 1478 :Converted FIXED field to DYNAMIC to enable on-line ADD COLUMN (no replies)

Hi,

I have a table having 85 columns (int, small int,tiny int, char, varchar type fields) with ndbcluster storage engine; I am executing following command by mysql client for adding a new column to the table:-

alter table TEST_TABLE add column COLUMN_1 int(11);

Then getting the following Warning:-

Thanks !!!
