…ion) Author: Patrick Wendell <pwendell@gmail.com> Closes #57 from pwendell/jekyll-prod-0.9 and squashes the following commits: 69a7614 [Patrick Wendell] Add Jekyll tag to isolate "production-only" doc components.

Refactor BlockId into an actual type Converts all of our BlockId strings into actual BlockId types. Here are some advantages of doing this now: + Type safety + Code clarity - it's now obvious what the key of a shuffle or rdd block is, for instance. Additionally, appearing in tuple/map type signatures is a big readability bonus. A Seq[(String, BlockStatus)] is not very clear. Further, we can now use more Scala features, like matching on BlockId types. + Explicit usage - we can now formally tell where various BlockIds are being used (without doing string searches); this makes updating current BlockIds a much clearer process, and compiler-supported. (I'm looking at you, shuffle file consolidation.) + It will only get harder to make this change as time goes on. Downside is, of course, that this is a very invasive change touching a lot of different files, which will inevitably lead to merge conflicts for many.

…conf ## What changes were proposed in this pull request? This is an effort to reduce the difference between Hive and Spark. Spark supports case-sensitivity in columns. Especially, for Struct types, with `spark.sql.caseSensitive=true`, the following is supported. ```scala scala> sql("select named_struct('a', 1, 'A', 2).a").show +--------------------------+ |named_struct(a, 1, A, 2).a| +--------------------------+ | 1| +--------------------------+ scala> sql("select named_struct('a', 1, 'A', 2).A").show +--------------------------+ |named_struct(a, 1, A, 2).A| +--------------------------+ | 2| +--------------------------+ ``` And vice versa, with `spark.sql.caseSensitive=false`, the following is supported. ```scala scala> sql("select named_struct('a', 1).A, named_struct('A', 1).a").show +--------------------+--------------------+ |named_struct(a, 1).A|named_struct(A, 1).a| +--------------------+--------------------+ | 1| 1| +--------------------+--------------------+ ``` However, types are considered different. For example, SET operations fail. ```scala scala> sql("SELECT named_struct('a',1) union all (select named_struct('A',2))").show org.apache.spark.sql.AnalysisException: Union can only be performed on tables with the compatible column types. struct<A:int> <> struct<a:int> at the first column of the second table;; 'Union :- Project [named_struct(a, 1) AS named_struct(a, 1)apache#57] : +- OneRowRelation$ +- Project [named_struct(A, 2) AS named_struct(A, 2)apache#58] +- OneRowRelation$ ``` This PR aims to support case-insensitive type equality. For example, in Set operation, the above operation succeed when `spark.sql.caseSensitive=false`. ```scala scala> sql("SELECT named_struct('a',1) union all (select named_struct('A',2))").show +------------------+ |named_struct(a, 1)| +------------------+ | [1]| | [2]| +------------------+ ``` ## How was this patch tested? Pass the Jenkins with a newly add test case. Author: Dongjoon Hyun <dongjoon@apache.org> Closes apache#18460 from dongjoon-hyun/SPARK-21247.
