我有一个pysparkDataframe，列值作为一个列表。我需要用基于另一个python列表的索引替换列表中的值

outer_list = [b,c,a,e,f,d]
+--------------------+--------------------+
|             USER_ID|            OFFERIDS|
+--------------------+--------------------+
| X                  + [a,b,c]            | 
+--------------------+--------------------+
| Y                  + [d,e,f]            |
+--------------------+--------------------+

+--------------------+--------------------+--------------------+
|             USER_ID|            OFFERIDS|             INDEXED|
+--------------------+--------------------+--------------------+          
| X                  + [a,b,c]            |        [2,0,1]     |
+--------------------+--------------------+--------------------+ 
| Y                  + [d,e,f]            |        [5,3,4]     |
+--------------------+--------------------+--------------------+

在pyspark中创建自定义项不起作用

replace_index = udf(lambda x:  [outer_list.index(offer) for offer in x if offer in outer_list ], ArrayType(IntegerType()) )

谁能帮我一下，我哪里出错了

userid_offerid_index = df.withColumn('INDEXED_OFFERIDS', replace_index('OFFERIDS'))
