Append a constant using modify stage

[sumoka]

Hi ,

is it possible to append a string at the beginning of a column in the modify stage ?

if it is used as a job parameter ?

e.g. i/p is a char column & I want to append a string 'AA' to every column.

Thanks in advance .

trying it,

I have initialized the constant string as a job parameter.

my concern is , can we pass an input parameter as a job parameter ?
