Running SparkPi

[Venkat Nagaswamy]

Hi

I am new to Spark and I am trying to run the example SparkPi.  I get the following error after a bunch of INFO messages.

Exception in thread "main" java.lang.NullPointerException

at java.net.URI$Parser.parse(URI.java:3004)

at java.net.URI.<init>(URI.java:577)

at spark.SparkContext.addJar(SparkContext.scala:511)

at spark.SparkContext$$anonfun$2.apply(SparkContext.scala:102)

at scala.collection.LinearSeqOptimized$class.foreach(LinearSeqOptimized.scala:59)

at scala.collection.immutable.List.foreach(List.scala:76)

at spark.SparkContext.<init>(SparkContext.scala:102)

at spark.examples.SparkPi$.main(SparkPi.scala:14)

at spark.examples.SparkPi.main(SparkPi.scala)

I am running scala-2.9.3 (through macports) and Spark0.7.2 (with a clean sbt/sbt clean package install).  I am running it on Mountain Lion.  The directory examples/target has only the scala-2.9.3 directory which in turn has spark-examples_2.9.3-0.7.2.jar.  There are no other jars in the scala-2.9.3 directory.

Any help would be greatly appreciated.

Thanks

Venkat

Looks like you might not have set the SPARK_EXAMPLES_JAR env variable
to point to the example jar.
spark master has been fixed to warn user about missing jar - but not
abort with an exception when it can recover.
