Failed to Read data from Couchbase using Spark - apache-spark

Question

I have been trying to read data from couchbase , but failing to read due to authentication issue.
import com.couchbase.client.java.document.JsonDocument
import org.apache.spark.sql.SparkSession
import com.couchbase.spark._
object SparkRead {
def main(args: Array[String]): Unit = {
// The SparkSession is the main entry point into spark
val spark = SparkSession
.builder()
.appName("KeyValueExample")
.master("local[*]") // use the JVM as the master, great for testing
.config("spark.couchbase.nodes", "***********") // connect to couchbase on hostname
.config("spark.couchbase.bucket.beer-sample","") // open the travel-sample bucket with empty password
.config("spark.couchbase.username", "couchdb")
.config("spark.couchbase.password", "******")
.config("spark.couchbase.connectTimeout","30000")
.config("spark.couchbase.kvTimeout","10000")
.config("spark.couchbase.socketConnect","10000")
.getOrCreate()
spark.sparkContext
.couchbaseGet[com.couchbase.client.java.document.JsonDocument](Seq("airline_10123")) // Load documents from couchbase
.collect() // collect all data from the spark workers
.foreach(println) // print each document content
}
}

Sample Code :
import com.couchbase.client.java.document.JsonDocument
import com.couchbase.spark._
import org.apache.spark.sql.SparkSession
object SparkReadCouchBase {
def main(args: Array[String]): Unit = {
val spark = SparkSession
.builder()
.appName("KeyValueExample")
.master("local[*]") // use the JVM as the master, great for testing
.config("spark.couchbase.nodes", "127.0.0.1") // connect to couchbase on hostname
.config("spark.couchbase.bucket.travel-sample","") // open the travel-sample bucket with empty password
.config("com.couchbase.username", "*******")
.config("com.couchbase.password", "*******")
.config("com.couchbase.kvTimeout","10000")
.config("com.couchbase.connectTimeout","30000")
.config("com.couchbase.socketConnect","10000")
.getOrCreate()
println("=====================================================================================")
spark.sparkContext
.couchbaseGet[JsonDocument](Seq("airline_10123")) // Load documents from couchbase
.collect() // collect all data from the spark workers
.foreach(println) // print each document content
println("=====================================================================================")
}

Answer 2

You will need to set the following couchbase configurations as system properties:
System.setProperty("com.couchbase.connectTimeout", "30000");
System.setProperty("com.couchbase.kvTimeout", "10000");
System.setProperty("com.couchbase.socketConnect", "10000");
