I am new to scale and spark
need help in subtracting one rdd from another by ignoring a field

rdd1.take(2) 

/*
[{'uuid': 'uuid1',
  'Id ': 1,
  'Name': ‘jack’},
 {'uuid': 'uuid2',
  'Id': 0,
  'Name': ‘Jill’}]
*/

2nd RDD

rdd2.take(2)

/*
[{'uuid': 'uuid3',
  'Id ': 1,
  'Name': ‘jack’},
 {'uuid': 'uuid4',
  'Id': 0,
  'Name': ‘Jill’}]
*/

I want to subtract 2nd RDD from 1st by ignoring field uuid.
The result of rdd1.subtract(rdd2) should be empty

How can i achieve thus
