    Tarantool connector for Apache Spark.

    Tarantool connector for Apache Spark.

    Call tarantoolSpace method on the SparkContext object to create a TarantoolRDD exposing Tarantool space as a Spark RDD.

    Example:

    Execute the following on a Cartridge router node (the tarantool/crud module must be installed):

    local crud = require('crud')

crud.insert('test_space', {1, nil, 'a1', 'Don Quixote', 'Miguel de Cervantes', 1605})
crud.insert('test_space', {2, nil, 'a2', 'The Great Gatsby', 'F. Scott Fitzgerald', 1925})
crud.insert('test_space', {3, nil, 'a3', 'War and Peace', 'Leo Tolstoy', 1869})

    Write the following in your Java client code:

    import io.tarantool.spark.connector._

val sparkMasterHost = "127.0.0.1"
val tarantoolRouterAddress = "127.0.0.1:3301"
val space = "test_space"

// Populate the Spark config with the address of a Cartridge router node and credentials:
val conf = new SparkConf(true)
conf.set ("tarantool.username", "admin")
conf.set ("tarantool.password", "testapp-cluster-cookie")
conf.set ("tarantool.hosts", tarantoolRouterAddress)

// Connect to the Spark cluster:
val sc = new SparkContext("spark://" + sparkMasterHost + ":7077", "example", conf)

// Read the space and print its contents:
val rdd = sc.tarantoolSpace(space)
rdd.toArray().foreach(println)

sc.stop()
