  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()
