Thomas Omans cd3176bd86 [SPARK-7743] [SQL] Parquet 1.7
Resolves [SPARK-7743](https://issues.apache.org/jira/browse/SPARK-7743).

Trivial changes of versions, package names, as well as a small issue in `ParquetTableOperations.scala`

```diff
-    val readContext = getReadSupport(configuration).init(
+    val readContext = ParquetInputFormat.getReadSupportInstance(configuration).init(
```

Since ParquetInputFormat.getReadSupport was made package private in the latest release.

Thanks

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.

TODO: apply type checking interface to more expressions.

Cheng Lian 686a45f0b9 [SPARK-8014] [SQL] Avoid premature metadata discovery when writing a HadoopFsRelation with a save mode other than Append
The current code references the schema of the DataFrame to be written before checking save mode. This triggers expensive metadata discovery prematurely. For save mode other than `Append`, this metadata discovery is useless since we either ignore the result (for `Ignore` and `ErrorIfExists`) or delete existing files (for `Overwrite`) later.

This PR fixes this issue by deferring metadata discovery after save mode checking.

Josh Rosen 0c33c7b4a6 [SPARK-7858] [SQL] Use output schema, not relation schema, for data source input conversion
In `DataSourceStrategy.createPhysicalRDD`, we use the relation schema as the target schema for converting incoming rows into Catalyst rows.  However, we should be using the output schema instead, since our scan might return a subset of the relation's columns.

This patch incorporates #6414 by liancheng, which fixes an issue in `SimpleTestRelation` that prevented this bug from being caught by our old tests:

> In `SimpleTextRelation`, we specified `needsConversion` to `true`, indicating that values produced by this testing relation should be of Scala types, and need to be converted to Catalyst types when necessary. However, we also used `Cast` to convert strings to expected data types. And `Cast` always produces values of Catalyst types, thus no conversion is done at all. This PR makes `SimpleTextRelation` produce Scala values so that data conversion code paths can be properly tested.

Closes #5986.

Andrew Or 5287eec5a6 [SPARK-7718] [SQL] Speed up partitioning by avoiding closure cleaning
According to yhuai we spent 6-7 seconds cleaning closures in a partitioning job that takes 12 seconds. Since we provide these closures in Spark we know for sure they are serializable, so we can bypass the cleaning.

Tathagata Das 3d0cccc858 [SPARK-7478] [SQL] Added SQLContext.getOrCreate
Having a SQLContext singleton would make it easier for applications to use a lazily instantiated single shared instance of SQLContext when needed. It would avoid problems like

1. In REPL/notebook environment, rerunning the line {{val sqlContext = new SQLContext}} multiple times created different contexts while overriding the reference to previous context, leading to issues like registered temp tables going missing.

2. In Streaming, creating SQLContext directly leads to serialization/deserialization issues when attempting to recover from DStream checkpoints. See [SPARK-6770]. Also to get around this problem I had to suggest creating a singleton instance - https://github.com/apache/spark/blob/master/examples/src/main/scala/org/apache/spark/examples/streaming/SqlNetworkWordCount.scala

This can be solved by {{SQLContext.getOrCreate}} which get or creates a new singleton instance of SQLContext using either a given SparkContext or a given SparkConf.

This PR together with #6285 should fix SPARK-7749.

Yin Huai b631bf73b9 [SPARK-7713] [SQL] Use shared broadcast hadoop conf for partitioned table scan.
https://issues.apache.org/jira/browse/SPARK-7713

I tested the performance with the following code:
```scala
import sqlContext._
import sqlContext.implicits._

(1 to 5000).foreach { i =>
  val df = (1 to 1000).map(j => (j, s"str$j")).toDF("a", "b").save(s"/tmp/partitioned/i=$i")
}

sqlContext.sql("""
CREATE TEMPORARY TABLE partitionedParquet
USING org.apache.spark.sql.parquet
OPTIONS (
  path '/tmp/partitioned'
)""")

table("partitionedParquet").explain(true)
```

In our master `explain` takes 40s in my laptop. With this PR, `explain` takes 14s.
