Apache-spark – Application report for application_ (state: ACCEPTED) never ends for Spark Submit (with Spark 1.2.0 on YARN)

amazon-emramazon-kinesisapache-sparkhadoop-yarn

I am running kinesis plus spark application
https://spark.apache.org/docs/1.2.0/streaming-kinesis-integration.html

I am running as below

command on ec2 instance :

 ./spark/bin/spark-submit --class org.apache.spark.examples.streaming.myclassname --master yarn-cluster --num-executors 2 --driver-memory 1g --executor-memory 1g --executor-cores 1  /home/hadoop/test.jar 

I have installed spark on EMR.

EMR details
Master instance group - 1   Running MASTER  m1.medium

Core instance group - 2 Running CORE    m1.medium

I am getting below INFO and it never ends.

Could somebody please let me know as why it's not working ?

Best Solution

I had this exact problem when multiple users were trying to run on our cluster at once. The fix was to change setting of the scheduler.

In the file /etc/hadoop/conf/capacity-scheduler.xml we changed the property yarn.scheduler.capacity.maximum-am-resource-percent from 0.1 to 0.5.

Changing this setting increases the fraction of the resources that is made available to be allocated to application masters, increasing the number of masters possible to run at once and hence increasing the number of possible concurrent applications.
