Review comment:
```
[info] Decoded objects do not match expected objects:
[info] expected: WrappedArray(0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10)
[info] actual: WrappedArray(9, 0, 10, 1, 2, 8, 3, 6, 7, 5, 4)
[info] assertnotnull(upcast(getcolumnbyordinal(0, LongType), LongType, -

[info] +- upcast(getcolumnbyordinal(0, LongType), LongType, - root class:
"scala.Long")
[info] +- getcolumnbyordinal(0, LongType) (QueryTest.scala:70)
```
We need to fix the read path of steaming output.
