Review Comment:
Are we using smaller memory in `PySpark` and `SparkR`?
Scala UT (Maven and SBT) seems to use small stack size, `4m`, at large
memory like `mx4g`.
```
-Xmx4g -Xss4m -XX:MaxMetaspaceSize=2g
```
Although this is already passed, do you think we can use more consistent
settings across Scala/Python/R?
