Dear all, I'm very new to Spark and I was trying to get acquainted with its basics using the tests in the documents.
Let me state first that I'm able to run everything using spark-shell also when I run it using a mesos master on a small cluster of 4 machines. I've tried to compile and run the example contained in the "A Standalone Job in Scala" section available here: " http://spark-project.org/docs/latest/quick-start.html";. As long as it concerns to run the job locally, everything works. I then modified the following line: val sc = new SparkContext("local", "Simple Job", "$YOUR_SPARK_HOME", List("target/scala-2.9.3/simple-project_2.9.3-1.0.jar")) into val sc = new SparkContext("mesos://xxx.yyy.zzz.it:5050[4]", "Simple Job", "$YOUR_SPARK_HOME", List("target/scala-2.9.3/simple-project_2.9.3-1.0.jar")) to run on the above mentioned cluster of four machines. Here's the issue: sbt run [...] 13/08/14 23:45:09 INFO spark.SparkContext: Added JAR target/scala-2.9.3/simple-project_2.9.3-1.0.jar at http://aaa.bbb.ccc.ddd:47683/jars/simple-project_2.9.3-1.0.jar with timestamp 1376516709537 Failed to load native Mesos library from /home/spark/BINs/spark-0.7.3/lib/java [error] (run-main) java.lang.UnsatisfiedLinkError: no mesos in java.library.path java.lang.UnsatisfiedLinkError: no mesos in java.library.path at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1878) at java.lang.Runtime.loadLibrary0(Runtime.java:849) at java.lang.System.loadLibrary(System.java:1087) at org.apache.mesos.MesosNativeLibrary.load(MesosNativeLibrary.java:46) at spark.SparkContext.<init>(SparkContext.scala:170) at SimpleJob$.main(SimpleJob.scala:8) at SimpleJob.main(SimpleJob.scala) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) 13/08/14 23:45:09 INFO network.ConnectionManager: Selector thread was interrupted! java.lang.RuntimeException: Nonzero exit code: 1 at scala.sys.package$.error(package.scala:27) [error] {file:/home/spark/DEMOs/SimpleJob/}default-031d15/compile:run: Nonzero exit code: 1 [error] Total time: 4 s, completed Aug 14, 2013 11:45:09 PM I've looked around and apparently I cannot find any help. Thanks in advance f
