-----------------------------------

[~maropu] in this case ,we can't read  memory dataset directly ,we should  read 
data from file,and set spark.sql.subexpressionElimination.enabled to true  
,because  read memory dataset directly  spark will optimize plan 

> GeneratePredicate eliminate will fail  in some case
