Re: Spark shuffle service does not work in stand alone

2015-10-13 Thread Jean-Baptiste Onofré 

Hi,

AFAIK, the shuffle service makes sense only to delegate the shuffle to 
mapreduce (as mapreduce shuffle is most of the time faster than the 
spark shuffle).

As you run in standalone mode, shuffle service will use the spark shuffle.

Not 100% thought.

Regards
JB

It would probably be more helpful if you looked for the executor error and
posted it. The screenshot you posted is the driver exception caused by the
task failure, which is not terribly useful.

I believe the confusion here is self-answered.
The thing is that in the documentation, the spark shuffle service runs only 
under YARN, while here we are speaking about a stand alone cluster.

The proper question is, how to launch a shuffle service for stand alone?

Re: Spark shuffle service does not work in stand alone

2015-10-13 Thread Marcelo Vanzin 
You have to manually start the shuffle service if you're not running YARN.
See the "sbin/start-shuffle-service.sh" script.

Thanks, I missed that one.

You have to manually start the shuffle service if you're not running YARN. See 
the "sbin/start-shuffle-service.sh" script.

I believe the confusion here is self-answered.
The thing is that in the documentation, the spark shuffle service runs only 
under YARN, while here we are speaking about a stand alone cluster.

The proper question is, how to launch a shuffle service for stand alone?

Hi, thanks

Executors are simply failing to connect to a shuffle server:
