Thanks. Added this to both the client and the master but still not getting any
more information. I confirmed the flag with ps.

There seems to be a version mismatch somewhere. You can try and find out the
cause with debug serialization information. I think the jvm flag
-Dsun.io.serialization.extendedDebugInfo=true should help.

I wrote a very simple Spark 1.4.1 app that I can run through a local driver
program just fine using setMaster(“local[*]”). The app is as follows:
import org.apache.spark.SparkContext
import org.apache.spark.SparkContext._
import org.apache.spark.SparkConf
import org.apache.spark.rdd.RDD
object Hello {
def main(args: Array[String]): Unit = {
val conf = new SparkConf().setAppName("Simple
Application").setMaster("local[*]")
val sc = new SparkContext(conf)
val data:RDD[Int] = sc.parallelize(Seq(1,2,12,34,2354,123,100), 2)
println("Max: " + data.max)
println("Min: " + data.min)
}
}
I compile this using the following build.sbt which will pull the needed Spark
libraries for me.
name := """SparkyJeff"""
version := "1.0"
scalaVersion := "2.11.6"
// Change this to another test framework if you prefer
libraryDependencies ++= Seq(
"org.apache.spark" %% "spark-core" % "1.4.1",
"org.apache.spark" %% "spark-sql" % "1.4.1")
// Uncomment to use Akka
//libraryDependencies += "com.typesafe.akka" %% "akka-actor" % "2.3.11"
fork := true
Now I’m trying to run this against a standalone cluster by changing the
setMaster(“local[*]”) to setMaster(“spark://p3.ourdomain.com:7077”). I
downloaded Spark 1.4.1 for Hadoop 2.6 or greater. Set the
SPARK_MASTER_IP=”p3.ourdomain.com<http://p3.ourdomain.com>”,
SPARK_WORKER_CORES=”1000”,SPARK_WORKER_MEMORY=”500g” and then started the
cluster using run-all.sh. The cluster appears to start fine. I can hit cluster
UI at p3.ourdomain.com:8080<http://p3.ourdomain.com:8080> and see the same
master URL as mentioned above.
Now when I run my little app I get the following client error:
…
