I don't think that was the problem, I changed the code as below and it worked. The issue was in toDF method: import org.apache.spark.SparkContext import org.apache.spark.SparkContext._ import org.apache.spark.sql._ import org.apache.spark.sql.types._ import org.apache.spark.SparkConf import sys.process._ class cc extends Runnable{ val conf = new SparkConf().setAppName("LoadDW") val sc = new SparkContext(conf) val sqlContext= new org.apache.spark.sql.SQLContext(sc) import sqlContext.implicits._ override def run(): Unit = { var fileName = "DimCustomer.txt" val fDimCustomer = sc.textFile("DimCustomer.txt") val schemaString = "ID Name City EffectiveFrom EffectiveTo" val schema = StructType(List( StructField("ID", IntegerType, true), StructField("Name", StringType, true), StructField("City", StringType, true), StructField("EffectiveFrom", IntegerType, true), StructField("EffectiveTo", IntegerType, true) ) ) println("----->>>>>>sdsdsd2222\n") var dimCustomerRDD = fDimCustomer.map(_.split(',')).map(r=>Row(r(0).toInt,r(1),r(2),r(3).toInt,r(4).toInt)) var customerDataFrame = sqlContext.createDataFrame(dimCustomerRDD, schema) customerDataFrame.registerTempTable("Cust_1") val customers = sqlContext.sql("select * from Cust_1") customers.show() println("+") } } object pp extends App { val cp = new cc() val rThread = new Thread (cp) rThread.start() }

Hi guys, I am trying to create a thread that creates a Data Frame from a text file and shows its content using the following code. It compiles successfully, but throws Task Not Serializable exception when I run it. Any suggestion how to make it work? Thanks for your time in advance. import org.apache.spark.SparkContext import org.apache.spark.SparkContext._ import org.apache.spark.sql._ import org.apache.spark.SparkConf import sys.process._ class cc extends Runnable{ case class DimC(ID:Int, Name:String, City:String, EffectiveFrom:Int, EffectiveTo:Int) val conf = new SparkConf().setAppName("LoadDW") val sc = new SparkContext(conf) val sqlContext= new org.apache.spark.sql.SQLContext(sc) import sqlContext.implicits._ override def run(): Unit = { var fileName = "DimCustomer.txt" val fDimCustomer = sc.textFile("DimCustomer.txt") println("----->>>>>>IN\n") var dimCustomer1 = fDimCustomer.map(_.split(',')).map(r=>DimC(r(0).toInt,r(1),r(2),r(3).toInt,r(4).toInt)).toDF dimCustomer1.registerTempTable("Cust_1") val customers = sqlContext.sql("select * from Cust_1") customers.show() } } object pp extends App { val cp = new cc() val rThread = new Thread (cp) rThread.start() }

Ok, I finally fixed the issue. 2 things needed to be done: 1- Import implicits: Note that this should be done only after an instance of org.apache.spark.sql.SQLContext is created. It should be written as: val sqlContext= new org.apache.spark.sql.SQLContext(sc) import sqlContext.implicits._ 2- Move case class outside of the method: case class, by use of which you define the schema of the DataFrame, should be defined outside of the method needing it. You can read more about it here: https://issues.scala-lang.org/browse/SI-6649 Cheers.

I tried every combination of capitalizations. None of them works. I reckon the key to notice is that, when I use "import sqlContext.implicits._" in spark-shell, and then run: case class DimC(ID:Int, Name:String, City:String, EffectiveFrom:Int, EffectiveTo:Int) It throws the error below. But it works perfectly the second time and creates the class. 15/07/21 04:48:12 INFO HiveMetaStore: 0: Opening raw store with implemenation class:org.apache.hadoop.hive.metastore.ObjectStore 15/07/21 04:48:12 INFO ObjectStore: ObjectStore, initialize called 15/07/21 04:48:12 WARN General: Plugin (Bundle) "org.datanucleus.api.jdo" is already registered.
