我正在尝试从Spark RDD执行插入到Ignite缓存中.我使用的是Ignite的2.2版和Spark的2.1版.

我采取的第一步是在单独的scala脚本中创建缓存,如下所示:

object Create_Ignite_Cache {

case class Custom_Class(
                   @(QuerySqlField @field)(index = true)   a: String,
                   @(QuerySqlField @field)(index = true)  b: String,
                   @(QuerySqlField @field)(index = true)  c: String,
                   @(QuerySqlField @field)(index = true)  d: String,
                   @(QuerySqlField @field)(index = true)  e: String,
                   @(QuerySqlField @field)(index = true)  f: String,
                   @(QuerySqlField @field)(index = true)  g: String,
                   @(QuerySqlField @field)(index = true)  h: String

                 )
def main(args: Array[String]): Unit = {
 val spi = new TcpDiscoverySpi
 val ipFinder = new TcpDiscoveryMulticastIpFinder
 val adresses = new util.ArrayList[String]
 adresses.add("127.0.0.1:48500..48520") …
