> Correctly parse dot notations for accessing an array of structs
> ---------------------------------------------------------------
>
> Key: SPARK-2096
> URL: https://issues.apache.org/jira/browse/SPARK-2096
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 1.0.0
> Reporter: Yin Huai
> Priority: Minor
> Labels: starter
>
> For example, "arrayOfStruct" is an array of structs and every element of this
> array has a field called "field1". "arrayOfStruct[0].field1" means to access
> the value of "field1" for the first element of "arrayOfStruct", but the SQL
> parser (in sql-core) treats "field1" as an alias. Also,
> "arrayOfStruct.field1" means to access all values of "field1" in this array
> of structs and the returns those values as an array. But, the SQL parser
> cannot resolve it.
