Step1: Update a column with null/'' value . Upsert into abc.tablename (Rowkeycombo1, Rowkeycombo2, columnname) values (123,to_date('1988-08-06'),null);
This works fine and the column then appears to have no data while doing a select.
Step2:Update the same column with a valid value. Upsert into abc.tablename (Rowkeycombo1, Rowkeycombo2, columnname) values (123,to_date('1988-08-06'),'TRYVAL'); Shows 1 row affected but the column still appears null/empty.
However there is no issue while updating a column which has a valid value to any other value.
I'm very new to Phoenix and hbase so I'm at a loss here.
