spark missing from status#631,bitrate#624 in operator !

操作过程：

val playCount = spark.sql(sqlPlay) //.cache()
val preview=playCount.filter("item_type like '%-P'")
val record1=playCount.except(preview)
上面这句从一个对象获取另外一批的df 使用except方法就报错，改为下面这样就通过了
//val record=playCount.filter("item_type in ('FTD','RTD')")
