The original test is passed because the class cast is lazy (only when the object's method is invoked).

This PR removes Hive windows functions from Spark and replaces them with (native) Spark ones. The PR is on par with Hive in terms of features.
This has the following advantages:
* Better memory management.
* The ability to use spark UDAFs in Window functions.

Since we rename the column name from ```text``` to ```value``` for DataFrame load by ```SQLContext.read.text```, we need to update doc.

For API DataFrame.join(right, usingColumns, joinType), if the joinType is right_outer or full_outer, the resulting join columns could be wrong (will be null).
The order of columns had been changed to match that with MySQL and PostgreSQL [1].
This PR also fix the nullability of output for outer join.

This PR makes JSON parser and schema inference handle more cases where we have unparsed records. It is based on #10043. The last commit fixes the failed test and updates the logic of schema inference.
Regarding the schema inference change, if we have something like
```
{"f1":1}
[1,2,3]
```
originally, we will get a DF without any column.
After this change, we will get a DF with columns `f1` and `_corrupt_record`. Basically, for the second row, `[1,2,3]` will be the value of `_corrupt_record`.

when invFunc is None, `reduceByKeyAndWindow(func, None, winsize, slidesize)` is equivalent to
reduceByKey(func).window(winsize, slidesize).reduceByKey(winsize, slidesize)
and no checkpoint is necessary. The corresponding Scala code does exactly that, but Python code always creates a windowed stream with obligatory checkpointing. The patch fixes this.
I do not know how to unit-test this.

Author: tedyu <yuzhihong@gmail.com>
Closes#10325 from ted-yu/master.
`DAGSchedulerEventLoop` normally only logs errors (so it can continue to process more events, from other jobs). However, this is not desirable in the tests -- the tests should be able to easily detect any exception, and also shouldn't silently succeed if there is an exception.
This was suggested by mateiz on https://github.com/apache/spark/pull/7699. It may have already turned up an issue in "zero split job".

Currently ORC filters are not tested properly. All the tests pass even if the filters are not pushed down or disabled. In this PR, I add some logics for this.
Since ORC does not filter record by record fully, this checks the count of the result and if it contains the expected values.

Based on the suggestions from marmbrus cloud-fan in https://github.com/apache/spark/pull/10165 , this PR is to print the decoded values(user objects) in `Dataset.show`
```scala
implicit val kryoEncoder = Encoders.kryo[KryoClassData]
val ds = Seq(KryoClassData("a", 1), KryoClassData("b", 2), KryoClassData("c", 3)).toDS()
ds.show(20, false);
```
The current output is like
```
+--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
|value |
+--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
|[1, 0, 111, 114, 103, 46, 97, 112, 97, 99, 104, 101, 46, 115, 112, 97, 114, 107, 46, 115, 113, 108, 46, 75, 114, 121, 111, 67, 108, 97, 115, 115, 68, 97, 116, -31, 1, 1, -126, 97, 2]|

After the fix, it will be like the below if and only if the users override the `toString` function in the class `KryoClassData`
```scala
override def toString: String = s"KryoClassData($a, $b)"
```
```
+-------------------+
|value |
+-------------------+
|KryoClassData(a, 1)|
|KryoClassData(b, 2)|
|KryoClassData(c, 3)|
+-------------------+
```
If users do not override the `toString` function, the results will be like
```
+---------------------------------------+
|value |
+---------------------------------------+
|org.apache.spark.sql.KryoClassData68ef|
|org.apache.spark.sql.KryoClassData6915|
|org.apache.spark.sql.KryoClassData693b|

SPARK_HOME is now causing problem with Mesos cluster mode since spark-submit script has been changed recently to take precendence when running spark-class scripts to look in SPARK_HOME if it's defined.
We should skip passing SPARK_HOME from the Spark client in cluster mode with Mesos, since Mesos shouldn't use this configuration but should use spark.executor.home instead.
