Hi,
I have an issue using Spark Streaming with a Spark Standalone cluster, my
job is well submitted but the workers seem to be unreachable. To build the
project I'musing sbt-assembly. My version of spark is 1.6.0.
here is my streaming conf:
val sparkConf = new SparkConf()
.setAppName("TwitterTags")
.setMaster("spark://master-IP:7077")
.set("spark.serializer", classOf[KryoSerializer].getName)
.setJars(Array("/root/E-Reputation/target/scala-2.10/E-Reputation-assembly-1.0-SNAPSHOT.jar"))
.setSparkHome("/root/spark-1.6.0/")
.set("spark.driver.extraClassPath",
"/root/E-Reputation/target/scala-2.10/E-Reputation-assembly-1.0-SNAPSHOT.jar")
val ssc = new StreamingContext(sparkConf, Seconds(6))
And this is the stderr of one of the workers of the cluster (it the same
stderr for all the workers):
16/03/14 14:29:35 WARN NativeCodeLoader: Unable to load native-hadoop
library for your platform... using builtin-java classes where applicable

Any ideas?
Many thanks
