Hello,
I wish to calculate the most recent event time from a Stream.

Hi,
This works for me
scala> val wSpec3 =
Window.partitionBy('priceInfo.getItem("ticker")).orderBy('priceInfo.getItem("timeissued").desc).rangeBetween(0,5)
wSpec3: org.apache.spark.sql.expressions.WindowSpec =

I’m beginning to agree with you and find it rather surprising that this is
mentioned nowhere explicitly (maybe I missed?). It is possible to serialize
code to be executed in executors to various nodes. It also seems possible
to serialize the “driver” bits of code although I’m not sure how the

In the GUI while the job is running the app-id link brings up logs to both
executors, The “name” link goes to 4040 of the machine that launched the
job but is not resolvable right now so the page is not shown. I’ll try the
netstat but the use of port 4040 was a good clue.
By what you say below thi
