I am running the following command on a Hadoop cluster to launch Spark shell with DRA: spark-shell --conf spark.dynamicAllocation.enabled=true --conf spark.shuffle.service.enabled=true --conf spark.dynamicAllocation.minExecutors=4 --conf spark.dynamicAllocation.maxExecutors=12 --conf spark.dynamicAllocation.sustainedSchedulerBacklogTimeout=120 --conf spark.dynamicAllocation.schedulerBacklogTimeout=300 --conf spark.dynamicAllocation.executorIdleTimeout=60 --executor-memory 512m --master yarn-client --queue default
This is the code I'm running within the Spark Shell - just demo stuff from teh web site. import org.apache.spark.mllib.clustering.KMeans import org.apache.spark.mllib.linalg.Vectors // Load and parse the data val data = sc.textFile("hdfs://ns/public/sample/kmeans_data.txt") val parsedData = data.map(s => Vectors.dense(s.split(' ').map(_.toDouble))).cache() // Cluster the data into two classes using KMeans val numClusters = 2 val numIterations = 20 val clusters = KMeans.train(parsedData, numClusters, numIterations) This works fine on Spark 1.4.1 but is failing on Spark 1.5.1. Did something change that I need to do differently for DRA on 1.5.1? This is the error I am getting: 15/10/29 21:44:19 WARN YarnScheduler: Initial job has not accepted any resources; check your cluster UI to ensure that workers are registered and have sufficient resources 15/10/29 21:44:34 WARN YarnScheduler: Initial job has not accepted any resources; check your cluster UI to ensure that workers are registered and have sufficient resources 15/10/29 21:44:49 WARN YarnScheduler: Initial job has not accepted any resources; check your cluster UI to ensure that workers are registered and have sufficient resources That happens to be the same error you get if you haven't followed the steps to enable DRA, however I have done those and as I said if I just flip to Spark 1.4.1 on the same cluster it works with my YARN config.
