Davies Liu 77da5be6f1 [SPARK-8610] [SQL] Separate Row and InternalRow (part 2)
Currently, we use GenericRow both for Row and InternalRow, which is confusing because it could contain Scala type also Catalyst types.

This PR changes to use GenericInternalRow for InternalRow (contains catalyst types), GenericRow for Row (contains Scala types).

Also fixes some incorrect use of InternalRow or Row.

Wenchen Fan b71d3254e5 [SPARK-8075] [SQL] apply type check interface to more expressions
a follow up of https://github.com/apache/spark/pull/6405.
Note: It's not a big change, a lot of changing is due to I swap some code in `aggregates.scala` to make aggregate functions right below its corresponding aggregate expressions.

Davies Liu d46f8e5d4b [SPARK-7186] [SQL] Decouple internal Row from external Row
Currently, we use o.a.s.sql.Row both internally and externally. The external interface is wider than what the internal needs because it is designed to facilitate end-user programming. This design has proven to be very error prone and cumbersome for internal Row implementations.

As a first step, we create an InternalRow interface in the catalyst module, which is identical to the current Row interface. And we switch all internal operators/expressions to use this InternalRow instead. When we need to expose Row, we convert the InternalRow implementation into Row for users.

For all public API, we use Row (for example, data source APIs), which will be converted into/from InternalRow by CatalystTypeConverters.

For all internal data sources (Json, Parquet, JDBC, Hive), we use InternalRow for better performance, casted into Row in buildScan() (without change the public API). When create a PhysicalRDD, we cast them back to InternalRow.

Davies Liu 5e7b6b67be [SPARK-8117] [SQL] Push codegen implementation into each Expression
This PR move codegen implementation of expressions into Expression class itself, make it easy to manage.

It introduces two APIs in Expression:
```
def gen(ctx: CodeGenContext): GeneratedExpressionCode
def genCode(ctx: CodeGenContext, ev: GeneratedExpressionCode): Code
```

gen(ctx) will call genSource(ctx, ev) to generate Java source code for the current expression. A expression needs to override genSource().

Here are the types:
```
type Term String
type Code String

/**
 * Java source for evaluating an [[Expression]] given a [[Row]] of input.
 */
case class GeneratedExpressionCode(var code: Code,
                               nullTerm: Term,
                               primitiveTerm: Term,
                               objectTerm: Term)
/**
 * A context for codegen, which is used to bookkeeping the expressions those are not supported
 * by codegen, then they are evaluated directly. The unsupported expression is appended at the
 * end of `references`, the position of it is kept in the code, used to access and evaluate it.
 */
class CodeGenContext {
  /**
   * Holding all the expressions those do not support codegen, will be evaluated directly.
   */

Wenchen Fan d38cf217e0 [SPARK-7562][SPARK-6444][SQL] Improve error reporting for expression data type mismatch
It seems hard to find a common pattern of checking types in `Expression`. Sometimes we know what input types we need(like `And`, we know we need two booleans), sometimes we just have some rules(like `Add`, we need 2 numeric types which are equal). So I defined a general interface `checkInputDataTypes` in `Expression` which returns a `TypeCheckResult`. `TypeCheckResult` can tell whether this expression passes the type checking or what the type mismatch is.

This PR mainly works on apply input types checking for arithmetic and predicate expressions.

Josh Rosen cafd5056e1 [SPARK-7691] [SQL] Refactor CatalystTypeConverter to use type-specific row accessors
This patch significantly refactors CatalystTypeConverters to both clean up the code and enable these conversions to work with future Project Tungsten features.

At a high level, I've reorganized the code so that all functions dealing with the same type are grouped together into type-specific subclasses of `CatalystTypeConveter`.  In addition, I've added new methods that allow the Catalyst Row -> Scala Row conversions to access the Catalyst row's fields through type-specific `getTYPE()` methods rather than the generic `get()` / `Row.apply` methods.  This refactoring is a blocker to being able to unit test new operators that I'm developing as part of Project Tungsten, since those operators may output `UnsafeRow` instances which don't support the generic `get()`.

The stricter type usage of types here has uncovered some bugs in other parts of Spark SQL:

- #6217: DescribeCommand is assigned wrong output attributes in SparkStrategies
- #6218: DataFrame.describe() should cast all aggregates to String
- #6400: Use output schema, not relation schema, for data source input conversion

Spark SQL current has undefined behavior for what happens when you try to create a DataFrame from user-specified rows whose values don't match the declared schema.  According to the `createDataFrame()` Scaladoc:

>  It is important to make sure that the structure of every [[Row]] of the provided RDD matches the provided schema. Otherwise, there will be runtime exception.

Given this, it sounds like it's technically not a break of our API contract to fail-fast when the data types don't match. However, there appear to be many cases where we don't fail even though the types don't match. For example, `JavaHashingTFSuite.hasingTF` passes a column of integers values for a "label" column which is supposed to contain floats.  This column isn't actually read or modified as part of query processing, so its actual concrete type doesn't seem to matter. In other cases, there could be situations where we have generic numeric aggregates that tolerate being called with different numeric types than the schema specified, but this can be okay due to numeric conversions.

In the long run, we will probably want to come up with precise semantics for implicit type conversions / widening when converting Java / Scala rows to Catalyst rows.  Until then, though, I think that failing fast with a ClassCastException is a reasonable behavior; this is the approach taken in this patch.  Note that certain optimizations in the inbound conversion functions for primitive types mean that we'll probably preserve the old undefined behavior in a majority of cases.

scwf 59250fe514 [SPARK-7303] [SQL] push down project if possible when the child is sort
Optimize the case of `project(_, sort)` , a example is:

`select key from (select * from testData order by key) t`

before this PR:
```
== Parsed Logical Plan ==
'Project ['key]
 'Subquery t
  'Sort ['key ASC], true
   'Project [*]
    'UnresolvedRelation [testData], None

== Analyzed Logical Plan ==
Project [key#0]
 Subquery t
  Sort [key#0 ASC], true
   Project [key#0,value#1]
    Subquery testData
     LogicalRDD [key#0,value#1], MapPartitionsRDD[1]

== Optimized Logical Plan ==
Project [key#0]
 Sort [key#0 ASC], true
  LogicalRDD [key#0,value#1], MapPartitionsRDD[1]

== Physical Plan ==
Project [key#0]
 Sort [key#0 ASC], true
  Exchange (RangePartitioning [key#0 ASC], 5), []
   PhysicalRDD [key#0,value#1], MapPartitionsRDD[1]
```

after this PR
```
== Parsed Logical Plan ==
'Project ['key]
 'Subquery t
  'Sort ['key ASC], true
   'Project [*]
    'UnresolvedRelation [testData], None

== Analyzed Logical Plan ==
Project [key#0]
 Subquery t
  Sort [key#0 ASC], true
   Project [key#0,value#1]
    Subquery testData
     LogicalRDD [key#0,value#1], MapPartitionsRDD[1]

== Optimized Logical Plan ==
Sort [key#0 ASC], true
 Project [key#0]
  LogicalRDD [key#0,value#1], MapPartitionsRDD[1]

== Physical Plan ==
Sort [key#0 ASC], true
 Exchange (RangePartitioning [key#0 ASC], 5), []
  Project [key#0]
   PhysicalRDD [key#0,value#1], MapPartitionsRDD[1]
```

with this rule we will first do column pruning on the table and then do sorting.
