Answer / rahul patil
All the above approaches are not correct because question was to join two flat files... if we use indirect file or unix command or joiner trns, we could only union two files but not join.
If we have file1 --- 100 records and
file2 --- 100 records then through above approaches we would have only 200 records.
But a join without join condition would return cartesian product and in our case count should be 10000.

Answer / murali udayagiri
Use join UNIX command in pre-session command for joining
both the files and write to a file. Use single SQ trans in
mapping to read that joined flat file data.
