Re: Configration Problem? (need help to get Spark job executed)
Hi
It could be due to the connectivity issue between the master and the slaves.
I have seen this issue occur for the following reasons.Are the slaves
visible in the Spark UI?And how much memory is allocated to the executors.
1. Syncing of configuration between Spark Master and Slaves.
2. Network connectivity issues between the master and slave.
Thanks

Hi all,
I am new to spark and seem to have hit a common newbie obstacle.
I have a pretty simple setup and job but I am unable to get past this
error when executing a job:
TaskSchedulerImpl: Initial job has not accepted any resources; check your
cluster UI to ensure that workers are registered and have sufficient memory”
I have so far gained a basic understanding of worker/executor/driver
memory, but have run out of ideas what to try next - maybe someone has a
clue.
My setup:
Three node standalone cluster with C* and spark on each node and the
Datastax C*/Spark connector JAR placed on each node.
On the master I have the slaves configured in conf/slaves and I am using
sbin/start-all.sh to start the whole cluster.
On each node I have this in conf/spark-defauls.conf
spark.masterspark://devpeng-db-cassandra-1:7077
spark.eventLog.enabled true
spark.serializer org.apache.spark.serializer.KryoSerializer
spark.executor.extraClassPath
/opt/spark-cassandra-connector-assembly-1.2.0-alpha1.jar
and this in conf/spart-env.sh
SPARK_WORKER_MEMORY=6g
My App looks like this
object TestApp extends App {
val conf = new SparkConf(true).set(spark.cassandra.connection.host,
devpeng-db-cassandra-1.)
val sc = new SparkContext(spark://devpeng-db-cassandra-1:7077,
testApp, conf)
val rdd = sc.cassandraTable(test, kv)
println(“Count: “ + String.valueOf(rdd.count) )
println(rdd.first)
}
Any kind of idea what to check next would help me at this point, I think.
