Having written a post on last Tuesday, I'm still not able to see my post
under nabble. And yeah, subscription to u...@apache.spark.org was
successful (rechecked a minute ago)
Even more, I have no way (and no confirmation) that my post was accepted,
rejected, whatever.
This is very L4M3 and so

Hi all,
# Programm Sketch
1. I create a HiveContext `hiveContext`
2. With that context, I create a DataFrame `df` from a JDBC relational
table.
3. I register the DataFrame `df` via
df.registerTempTable("TESTTABLE")
4. I start a HiveThriftServer2 via
When will window functions be integrated into Spark (without HiveContext?)

You will need to use a HiveContext for window functions to work.

DataFrame.printSchema. (or
at least I did not find a way of how to)

Dear Michael, dear all,
a minimal example is listed below.
After some further analysis I could figure out, that the problem is
related

//|-- y: integer (nullable = true)
//
//+-+---+-+-+
//|x| a|x|y|
//+-+---+-+-+
//|2|bob|2|5|
//+-+---+-+-+
}

Dear Michael, dear all,
distinguishing those records that have a match in mapping from those
anything to do with nullable,
which is only a hint to the system so that we can avoid null checking when
we know that there are no null values. If you provide the full code i can
try and see if this is a bug.

Dear Michael, dear all,
motivation:
object OtherEntities {
case class Record( x:Int, a: String)
case class Mapping( x: Int, y: Int )
val records = Seq( Record(1, hello), Record(2, bob))
val mappings = Seq( Mapping(2, 5) )
}
Now I want to perform an *left outer join* on records and
10 matches
