Description
If we run the following example the result is the expected equal 2 columns:
val c = rand() df.select(c, c) +--------------------------+--------------------------+ |rand(-4522010140232537566)|rand(-4522010140232537566)| +--------------------------+--------------------------+ | 0.4520819282997137| 0.4520819282997137| +--------------------------+--------------------------+
But if we run use other similar APIs their result is incorrect:
val r1 = random()
val r2 = uuid()
val r3 = shuffle(col("x"))
val x = df.select(r1, r1, r2, r2, r3, r3)
+------------------+------------------+--------------------+--------------------+----------+----------+
| rand()| rand()| uuid()| uuid()|shuffle(x)|shuffle(x)|
+------------------+------------------+--------------------+--------------------+----------+----------+
|0.7407604956381952|0.7957319451135009|e55bc4b0-74e6-4b0...|a587163b-d06b-4bb...| [1, 2, 3]| [2, 1, 3]|
