@chenghao-intel Thanks! re-pro steps: (actually copied and adapted from
your patch :)
```
val data = (1 to 100000).map { i => (i, i, i) }
data.toDF("d1", "d2", "d3").registerTempTable("script_trans")
sql("SELECT TRANSFORM (d1, d2, d3) USING 'cat 1>&2' AS (a,b,c) FROM
script_trans").queryExecution.toRdd.count()
```
