Hello Tilak,
1. I get error Not found: type RDD error. Can someone please tell me which jars
do I need to add as external jars and what dhoulf I add iunder import
statements so that this error will go away.
Do you not see any issues with the import statements?
Add the spark-assembly-1.0.0-hadoop2.2.0.jar file as a dependency.
You can download Spark from here (http://spark.apache.org/downloads.html).
You'll find the above mentioned jar in the lib folder.
Import Statement: import org.apache.spark.rdd.RDD

Hi All,
I am new so Scala and Spark. I have a basic question. I have the following
import statements in my Scala program. I want to pass my function (printScore)
to Spark. It will compare a string
import org.apache.spark.SparkContext
import org.apache.spark.SparkContext._
import org.apache.spark.SparkConf
/* import thirdparty jars */
I have the following method in my Scala class:
class DistanceClass
{
val ta = new textAnalytics();
def printScore(sourceStr: String, rdd: RDD[String])
{
// Third party jars have StringWrapper
val str1 = new StringWrapper (sourceStr)
val ta_ = this.ta;
rdd.map(str1, x => ta_.score(str1, StringWrapper(x))
}
I am using Eclipse for development. I have the following questions:
1. I get error Not found: type RDD error. Can someone please tell me which jars
do I need to add as external jars and what dhoulf I add iunder import
statements so that this error will go away.
2. Also, including StringWrapper(x) inside map, will that be OK? rdd.map(str1,
x => ta_.score(str1, StringWrapper(x))
