You can only add columns at the end. If you are using the native SerDe try
ALTER TABLE tbl_name REPLACE COLUMNS (column1 int, mynewcolumn string, column2 int);

Adding a column by alter table mytable add column (mynewcolumn string); works well for me. This adds a field to the end of the schema.
Is there a way to add a column in between two columns?
