Unable to change/cast column datatype using Delta IO

[Srikanthn]

I have created a delta table using Delta IO library, with following details

Table Name: Employee

Columns {Id Integer, name String, gender String, Salary decimal(5,2)}

Now I want to upcast the salary from decimal(5,2) to decimal(10,4). If I use delta IO library I am endup with "Detected incompatible schema change" error. Is there way to change upcast columns, change datatype using Delta IO.
