Looks like you've got one more layer of containment than you intend -- i.e.
you've got Row[WrappedArray[Row[(Int, String)]] where you want
Row[Row[(Int, String)]]. That's easy to do if somewhere along the line you
did something like `val row = Row(collection)` instead of `val row =
Row.fromSeq(col
Hi Mark,
Thank you for helping out.
The items I got back from Spark SQL has the type information as follows:
scala> items
res16: org.apache.spark.sql.Row = [WrappedArray([1,orange],[2,apple])]
I tried to iterate the items as you suggested but no luck.

scala> val items = Row(1 -> "orange", 2 -> "apple")
items: org.apache.spark.sql.catalyst.expressions.Row =
[(1,orange),(2,apple)]
If you literally want an iterator, then this:
scala> items.toIterator.count { case (user_id, name) => user_id == 1 }
res0: Int = 1
...else:
scala> items.count
Hi spark users,
Do you know how to access rows of row?
I have a SchemaRDD called user and register it as a table with the

root
|-- user_id: string (nullable = true)
|-- item: array (nullable = true)
||-- element: struct (containsNull = false)
|||-- item_id: stri
