Best active groups, forums or contacts for Spark ?
Hi
It is very often difficult to get answers of question about Spark in many forums.. Maybe they are inactive or my questions are too bad. I don't know, but does anyone know good active groups, forums or contacts other like this ?

@Thanks Marco.
I have provided information in my original post (
http://apache-spark-user-list.1001560.n3.nabble.com/Spark-Standalone-Mode-application-runs-but-executor-is-killed-tc30739.html
<http://apache-spark-user-list.1001560.n3.nabble.com/Spark-Standalone-Mode-application-runs-but-executor-is-killed-tc30739.html>
) so as to keep the context of the ask for anyone looking for similar
information in future.

Hi
From personal experience....and I might be asking u obvious question
1. Does it work in standalone (no cluster)
2. Can u break down app in pieces and try to see at which step the code
gets killed?
3. Have u had a look at spark gui to see if we executors go oom?
I might be oversimplifying what spark does. But if ur logic works
standalone and does not work in cluster....the cluster might b ur
problem..(apart from modules not being serializable)
If it breaks in no cluster mode then it's easier to debug
I am no way an expert, just talking from my little personal experience.
I m sure someone here can give more hints on how to debug properly a spark
app

@Esa Thanks for posting this as I was thinking the same way when trying to
get some help about Spark (I am just a beginner)
@Jack
I posted a question @ here (
http://apache-spark-user-list.1001560.n3.nabble.com/Spark-Standalone-Mode-application-runs-but-executor-is-killed-tc30739.html
<http://apache-spark-user-list.1001560.n3.nabble.com/Spark-Standalone-Mode-application-runs-but-executor-is-killed-tc30739.html>
) and stackoverflow (
https://stackoverflow.com/questions/48445145/spark-standalone-mode-application-runs-but-executor-is-killed-with-exitstatus
<https://stackoverflow.com/questions/48445145/spark-standalone-mode-application-runs-but-executor-is-killed-with-exitstatus>
) and haven't received much of views or even a comment.
I am new to Spark and may be my question is framed badly.
Would you be able to take a look?

Hi Esa,
I'd say https://stackoverflow.com/questions/tagged/apache-spark is where
many active sparkians hang out :)
Pozdrawiam,
