Increase cores for yarn in Spark application

0 votes
I think the Yarn is too slow for the Spark application and I think there's some problem with the core. I want to increase the number of cores for Yarn application master. I am running Spark as a standalone application. Please help in increasing the number of cores, what code should I use?

By default, only one core is used for Yarn application master. To increase this, use the following command in the Spark shell:

val sc = new SparkContext(new SparkConf())

./bin/spark-submit <all your existing options> --spark.yarn.am.cores=<number of cores>
