> It is known that there isn't any exact median function in Spark SQL, and this might be
a difficult problem to solve efficiently. However, to find the median for an array should
be a simple task, and something that users can utilize when collecting numeric values to a
list or set.
> This can already be achieved by using sorting and choosing element, but can get cumbersome
and if a fully tested function is provided in the API, I think it can solve some headache
for many.
