Has anyone successfully followed the instructions on the Quick Start page of the Spark home page to run a "standalone" Scala application? I can't, and I figure I must be missing something obvious!
I'm trying to follow the instructions here as close to "word for word" as possible: http://spark.apache.org/docs/latest/quick-start.html#a-standalone-app-in-scala 1. The instructions don't say what directory to create my test application in, but later I'm instructed to run "sbt/sbt" so I conclude that my working directory must be $SPARK_HOME. (Temporarily ignoring that it is a little weird to be working directly in the Spark distro.) 2. Create $SPARK_HOME/mysparktest/src/main/scala/SimpleApp.scala. Copy&paste in the code from the instructions exactly, replacing YOUR_SPARK_HOME with my spark home path. 3. Create $SPARK_HOME/mysparktest/simple.sbt. Copy&paste in the sbt file from the instructions 4. From the $SPARK_HOME I run "sbt/sbt package". It runs through the ENTIRE Spark project! This takes several minutes, and at the end, it says "Done packaging". unfortunately, there's nothing in the $SPARK_HOME/mysparktest/ folder other than what I already had there. (Just for fun, I also did what I thought was more logical, which is set my working directory to $SPARK_HOME/mysparktest, and but $SPARK_HOME/sbt/sbt package, but that was even less successful: I got an error: awk: cmd. line:1: fatal: cannot open file `./project/build.properties' for reading (No such file or directory) Attempting to fetch sbt /usr/lib/spark/sbt/sbt: line 33: sbt/sbt-launch-.jar: No such file or directory /usr/lib/spark/sbt/sbt: line 33: sbt/sbt-launch-.jar: No such file or directory Our attempt to download sbt locally to sbt/sbt-launch-.jar failed. Please install sbt manually from http://www.scala-sbt.org/ So, help? I'm sure these instructions work because people are following them every day, but I can't tell what they are supposed to do. Thanks! Diana
