>From my understanding as soon as I use YARN I don't need to use parrallelisme >(at least for RDD treatment) I don't want to use direct stream as I have to manage the offset positionning (in order to be able to start from the last offset treated after a spark job failure)

Or use the direct stream. On Fri, Oct 2, 2015 at 10:40 AM, < [email protected] > wrote: Hello, I have a job receiving data from kafka (4 partitions) and persisting data inside MongoDB. It works fine, but when I deploy it inside YARN cluster (4 nodes with 2 cores) only on node is receiving all the kafka partitions and only one node is processing my RDD treatment (foreach function) How can I force YARN to use all the resources nodes and cores to process the data (receiver & RDD treatment) Tks a lot Nicolas --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected] --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
