Ambiguous references to id : what does it mean ?

[Jaonary Rabarisoa]

Hi all,

When running a join operation with Spark SQL I got the following error :


Exception in thread "main"
org.apache.spark.sql.catalyst.errors.package$TreeNodeException: Ambiguous
references to id: (id#303,List()),(id#0,List()), tree:
Filter ('videoId = 'id)
 Join Inner, None
  ParquetRelation data/tags.parquet
  Filter (name#1 = P1/cam1)
   ParquetRelation data/videos.parquet


What does it mean ?


Cheers,
