RE: Basic Scala and Spark questions
Hi there,Here is how I specify it during the compilation.
scalac -classpath
/apps/software/abc.jar:/apps/software/spark-1.0.0-bin-hadoop1/lib/datanucleus-api-jdo-3.2.1.jar:/apps/software/spark-1.0.0-bin-hadoop1/lib/spark-assembly-1.0.0-hadoop1.0.4.jar:spark-assembly-1.0.0-hadoop1.0.4.jar/datanucleus-core-3.2.2.jar
Score.scala
Then I generate a jar file out of it say myapp.
Finally, to run this I do the following:
./spark-shell --jars /apps/software/abc.jar,/apps/software/myapp/myapp.jar
Hope this helps.

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.

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))

RE: Basic Scala and Spark questions
Hi All,I was able to solve both these issues. Thanks!
Just FYI:
For 1:
import org.apache.spark.rdd;
import org.apache.spark.rdd.RDD;
For 2:
rdd.map(x => jc_.score(str1, new StringWrapper(x))) From:
