[PHP知识库]java.lang.NumberFormatException: For input string: ““ org.apache.spark.SparkException: : Task[scala]

User class threw exception: org.apache.spark.SparkException: Job aborted due to stage failure: Task 0 in stage 14.0 failed 4 times, most recent failure: Lost task 0.3 in stage 14.0 (TID 390, 9.54.136.125, executor 9): java.lang.NumberFormatException: For input string: "5326795854138346"

使用Scala语言报错，从网上找的资料可以知道，Int类型最长到10位数，而我输入的"5326795854138346"，远多于十位数，这时将他转成Int类型就报错，

?

可以这么改：

val data1 = data.map(_.toString.toLong)

一般要先转换成string类型 再转换
