报错代码

    spark.sql("""|select user_id, event, time, $title,|case when event = '$MPShow' then 1|when event = '$MPViewScreen' then 2|when event = '$MPClick' then 3|when event = '$MPHide' then 4|end as event_index ,|case when event = '$MPShow' then '小程序显示'|when event = '$MPViewScreen' then '小程序页面浏览'|when event = '$MPClick' then '小程序元素点击'|when event = '$MPHide' then '小程序进入后台'|end as label|from events|where event in ('$MPShow','$MPViewScreen','$MPClick','$MPHide') -- and time >= '...' and time <= '...'""".stripMargin).createTempView("roadmap1")

2.解决方案

spark sql中的字段名如果需要$title，则需要用`$title`，否则会报错。
