I use Mahout to run various algorithms,e.g. kmeans, and then I would like to use the result to plot graph. Im using R as my graph plotting tool. I use the seqsdumper and export format as graph_ml. However, the output file (graph ml ) contains difference result from csv output.r also cannot plot the result.
My question Anyway to plot the Mahout result by r 2016/2/3 上午12:22於 "BahaaEddin AlAila" <bahaelai...@gmail.com>寫道: > Greetings mahout users, > > I have been trying to use mahout samsara as a library with scala/spark, but > I haven't been successful in doing so. > > I am running spark 1.6.0 binaries, didn't build it myself. > However, I tried both readily available binaries on Apache mirrors, and > cloning and compiling mahout's repo, but neither worked. > > I keep getting > > Exception in thread "main" java.lang.NoClassDefFoundError: > org/apache/mahout/sparkbindings/SparkDistributedContext > > The way I am doing things is: > I have spark in ~/spark-1.6 > and mahout in ~/mahout > I have set both $SPARK_HOME and $MAHOUT_HOME accordingly, along with > $MAHOUT_LOCAL=true > > and I have: > > ~/app1/build.sbt > ~/app1/src/main/scala/App1.scala > > in build.sbt I have these lines to declare mahout dependecies: > > libraryDependencies += "org.apache.mahout" %% "mahout-math-scala" % > "0.11.1" > > libraryDependencies += "org.apache.mahout" % "mahout-math" % "0.11.1" > > libraryDependencies += "org.apache.mahout" % "mahout-spark_2.10" % "0.11.1" > > along with other spark dependencies > > and in App1.scala, in the main function, I construct a context object using > mahoutSparkContext, and of course, the sparkbindings are imported > > everything compiles successfully > > however, when I submit to spark, I get the above mentioned error. > > I have a general idea of why this is happening: because the compiled app1 > jar depends on mahout-spark dependency jar but it cannot find it in the > class path upon being submitted to spark. > > In the instructions I couldn't find how to explicitly add the mahout-spark > dependency jar to the class path. > > The question is: Am I doing the configurations correctly or not? > > Sorry for the lengthy email > > Kind Regards, > Bahaa >
