[~allisonwang-db] I test and cannot reproduce it.

{code:java}
  sql("select map(1, 2) as m_a, map(3, 4) as m_b").write.saveAsTable("t")
  val row = sql("select map_from_arrays(array(1, 2), array(m_a, m_b)) from 
t").first()
  assert(row.getMap[Int, Map[Int, Int]](0) === Map(1 -> Map(1 -> 2), 2 -> 
Map(3 -> 4)))
{code}
