This is our code:

I trained a xgboost model in spark scala as follows:
val xgbParamGrid = new ParamGridBuilder()
.addGrid(xgb.maxDepth, Array(5, 10))
.addGrid(xgb.maxBins, Array(2))
.addGrid(xgb.minChildWeight, Array(0.2))
.addGrid(xgb.eta, Array(0.015))
.addGrid(xgb.alpha, Array(0.8, 0.9))
.addGrid(xgb.lambda, Array(0.9, 1.0))
.build()
// Create the XGBoost pipeline
val pipeline = new Pipeline().setStages(Array(xgb))
val evaluator = new MulticlassClassificationEvaluator()
.setLabelCol("label")
.setPredictionCol("prediction")
.setMetricName("accuracy")
val cv = new CrossValidator()
.setEstimator(pipeline)
.setEvaluator(evaluator)
.setEstimatorParamMaps(xgbParamGrid)
.setNumFolds(3)
val xgbModel = cv.fit(trainingData)
val xgbBest = xgbModel.bestModel.asInstanceOf[PipelineModel].stages(0).asInstanceOf[XGBoostClassificationModel]
Then I tried to save it to local as:
xgbBest.write.overwrite.save(modelSavePath)
but got error message as:

Can anyone help with the problem? Thanks
I'm new to Spark & Scala and I got exception after calling saveAsTextFile(). Hope someone can help...
Here is my input.txt:
Hello World, I'm a programmer

This is the info after running "spark-shell" on CMD:

To adjust logging level use sc.setLogLevel(newLevel). For SparkR, use setLogLevel(newLevel).

From the Error logs. seems like you are using Spark on Windows. You can try for below troubleshooting steps:-
search for winuntils.exe path
cd path
winutils.exe chmod 777 output (directory where you store output)
Lets try again to store output (counts.saveAsTextFile("output"))
I think you need to specify the input file path correctly. Your input RDD is not getting created that's why its not able to create an output.
You should see as below:-
scala> val inputfile = sc.textFile("file:///home/lg552987/input.txt")
inputfile: org.apache.spark.rdd.RDD[String] = file:///home/lg552987/input.txt MapPartitionsRDD[5] at textFile at <console>:27
scala> val counts = inputfile.flatMap(line => line.split(" ")).map(word => (word, 1)).reduceByKey(_+_)
counts: org.apache.spark.rdd.RDD[(String, Int)] = ShuffledRDD[8] at reduceByKey at <console>:29
scala> counts.toDebugString
res0: String =
(2) ShuffledRDD[8] at reduceByKey at <console>:29 []
+-(2) MapPartitionsRDD[7] at map at <console>:29 []
| MapPartitionsRDD[6] at flatMap at <console>:29 []
| file:///home/lg552987/input.txt MapPartitionsRDD[5] at textFile at <console>:27 []
| file:///home/lg552987/input.txt HadoopRDD[4] at textFile at <console>:27 []
scala> counts.cache()
res1: counts.type = ShuffledRDD[8] at reduceByKey at <console>:29
scala> counts.saveAsTextFile("output")

i am new to spark and machine learning, so to practice i was trying to write a k-means algorithm in spark 1.6.0 using a dataset.
i was doing as specified in example on apache spark website.
while doing so i got this error :
java.lang.NumberFormatException: For input string: "2014-03-15:10:10:20,Sorrento,8cc3b47e-bd01-4482-b500-28f2342679af,33.6894754264,-1
17.543308253"
my code in which i got this error:

here is the link for data set: dataset
help me guys fix this error.
thanks in advance.
Referring to your input data
2014-03-15:10:10:20,Sorrento,8cc3b47e-bd01-4482-b500-28f2342679af,33.6894754264,-1 17.543308253
You are trying to get the double value (17.543308253), convert it to double and use it for Vectors.dense for machine learning.
If thats the case then you should be doing
val parsedData = rdd.map(s => Vectors.dense(s.split(' ')(1).toDouble)).cache()
If you do Vectors.dense(s.split(' ').map(_.toDouble)), you are trying to convert the 2014-03-15:10:10:20,Sorrento,8cc3b47e-bd01-4482-500-28f2342679af,33.6894754264,-1 of your data to double too, which would give you NumberFormatException
I hope the answer is helpful
I try to read data from a static textfile stored in HDFS, store its content into an ArrayBuffer which in turn should be broadcasted via sparkContext.broadcast as a BroadcastVariable. I am using cloudera's spark, spark version 1.6.0-cdh5.7.0 and spark-streaming_2.10.
I start the application on yarn using spark-submit:
spark-submit --class my.package.BroadcastStreamTest1 --master yarn --deploy-mode client --conf spark.executor.userClassPathFirst=true current.jar
When I do this, I get an
java.lang.ClassCastException: cannot assign instance of scala.Some to field org.apache.spark.Accumulable.name of type scala.Option in instance of org.apache.spark.Accumulator
The same code used with a hard coded ArrayBuffer work perfectly so I assume it has something to do with the static file resource...
Does anyone have an idea what I am possibly doing wrong? Any help appreciated.
This does not work:
object BroadcastStreamTest1 {
def main(args: Array[String]) {
val sparkConf = new SparkConf()
val streamingContext = new StreamingContext(sparkConf, batchDuration = Seconds(10))
val content = streamingContext.sparkContext
.textFile("hdfs:///data/someTextFile.txt")
.collect()
.toBuffer[String]
val broadCastVar = streamingContext.sparkContext.broadcast(content)
broadCastVar.value.foreach(line => println(line))
streamingContext.start()
streamingContext.awaitTermination()
}
}
This works:
object BroadcastStreamTest2 {
def main(args: Array[String]) {
val sparkConf = new SparkConf()
val streamingContext = new StreamingContext(sparkConf, batchDuration = Seconds(10))
val content = new mutable.ArrayBuffer[String]
(1 to 50).foreach(i => content += "line" + i)
val broadCastVar = streamingContext.sparkContext.broadcast(content)
broadCastVar.value.foreach(line => println(line))
streamingContext.start()
streamingContext.awaitTermination()
}
}

The reason was some kind of conflict with my provided jar file.
Without setting
spark.executor.userClassPathFirst=true
it works, unfortunately I could not locate the exact cause of the problem.
I am playing around with Scala's ProcessBuilder and I am trying to launch the bitcoin-cli from Scala.
This works fine from the shell and the command to execute it is simply bitcoin-cli
However if I try and launch it from the scala REPL I get an error:
