Xingjun Hao updated CARBONDATA-3643:
------------------------------------
    Description: 
 
{code:java}
//
sql("create table datatype_struct_parquet(price struct<b:array<string>>) stored 
as parquet") 
sql("insert into table datatype_struct_parquet values(named_struct('b', 
array('')))") 
sql("create table datatype_struct_carbondata(price struct<b:array<string>>) 
stored as carbondata") 
sql("insert into datatype_struct_carbondata select * from 
datatype_struct_parquet")

checkAnswer( sql("SELECT * FROM datatype_struct_carbondata"), sql("SELECT * 
FROM datatype_struct_parquet"))

!== Correct Answer - 1 == == Spark Answer - 1 == 
![[WrappedArray()]] [[WrappedArray(null)]]
{code}
 

  was:
sql("create table datatype_struct_parquet(price struct<b:array<string>>) stored 
as parquet")
 sql("insert into table datatype_struct_parquet values(named_struct('b', 
array('')))")
 sql("create table datatype_struct_carbondata(price struct<b:array<string>>) 
stored as carbondata")
 sql("insert into datatype_struct_carbondata select * from 
datatype_struct_parquet")

 
{code:java}
