如何将全局变量添加到地图操作中？

Question

在scala中，我试图将一个巨大的全局变量传递给map操作，spark提示我提供信息：

ERROR yarn.ApplicationMaster: User class threw exception: java.lang.StackOverflowError
at java.io.ObjectOutputStream.writeSerialData(ObjectOutputStream.java:1509)
at java.io.ObjectOutputStream.writeOrdinaryObject(ObjectOutputStream.java:1432)
at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1178)
at java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java:1548)

代码就像：

val data = sc.textFile(inputPath).cache()
val map = Map[String, Int]()
for (i <- 0 to 9) {
    map(i.toString) = i
}
data.map(sample => {
    if (map.contains(sample)) {
        ("Found")
    }
    else {
        ("Not found")
    }
})

它已经解决了，我调整了数据类型来自＆＃34;数组[Map [String，Int]]＆＃34;进入＆＃34; Map [String，Int]＆＃34;
