There was a problem hiding this comment.
What do you think about this?
val s = schema.get
s.fieldNames.intersect(partColNames).map(s.apply)

I'd rewrite the whole if as following:
for (s <- schema if partColNames.nonEmpty) {
append(buffer, "# Partition Information", "", "")
append(buffer, s"# ${output.head.name}", output(1).name, output(2).name)
describeSchema(StructType(partColNames.map(s(_))))
}
