比较DataFrame两列相等与不相等

import sparkSession.implicits._
val innerDataFrame = 某个DataFrame
val summuryAmountDiffDataFrame  = innerDataFrame.filter($"summary_amount" =!= $"summary_amount2").filter($"summary_count" === $"summary_count2")
// 或者
val summuryAmountDiffDataFrame2 = innerDataFrame.where("summary_amount != summary_amount2 AND summary_count == summary_count2")

注：
1、summary_amount、summary_amount2、summary_count、summary_count2是innerDataFrame的列；
2、一定要导入 import sparkSession.implicits._
