If anyone's there who appeared for the examination, can you kindly help?

1) What are the kind of questions that come,

2) Samples,

3) All the other details.

Thanks,
Aakash.

Replication join = broadcast join. Look for that term on google. Many examples.

Semi join can be done on dataframes/dataset by passing “semi join” as the third parameter on the join/joinWith function.

Not sure about the other two.
