This patch alters `InMemoryFileIndex` to filter out these `basePath`s whose ancestor is the streaming metadata dir (`_spark_metadata`). E.g., the following and other similar dir or files will be filtered out:
- (introduced by globbing `basePath/*`)
- `basePath/_spark_metadata`
- (introduced by globbing `basePath/*/*`)
- `basePath/_spark_metadata/0`
- `basePath/_spark_metadata/1`
- ...

## What changes were proposed in this pull request?
We allow users to specify hints (currently only "broadcast" is supported) in SQL and DataFrame. However, while SQL has a standard hint format (/*+ ... */), DataFrame doesn't have one and sometimes users are confused that they can't find how to apply a broadcast hint. This ticket adds a generic hint function on DataFrame that allows using the same hint on DataFrames as well as SQL.
As an example, after this patch, the following will apply a broadcast hint on a DataFrame using the new hint function:
```
df1.join(df2.hint("broadcast"))
```

Within the same streaming query, when one `StreamingRelation` is referred multiple times – e.g. `df.union(df)` – we should transform it only to one `StreamingExecutionRelation`, instead of two or more different `StreamingExecutionRelation`s (each of which would have a separate set of source, source logs, ...).

## What changes were proposed in this pull request?
To better understand this problem, let's take a look at an example first:
```
object Main {
def main(args: Array[String]): Unit = {
var t = new Test
new Thread(new Runnable {
override def run() = {}
}).start()
println("first thread finished")
t.a = null
t = new Test
new Thread(new Runnable {
override def run() = {}
}).start()
}
}
class Test {
var a = new InheritableThreadLocal[String] {
override protected def childValue(parent: String): String = {
println("parent value is: " + parent)
parent
}
}
a.set("hello")
}
```
The result is:
```
parent value is: hello
first thread finished
parent value is: hello
parent value is: hello
```
Once an `InheritableThreadLocal` has been set value, child threads will inherit its value as long as it has not been GCed, so setting the variable which holds the `InheritableThreadLocal` to `null` doesn't work as we expected.
In `SparkContext`, we have an `InheritableThreadLocal` for local properties, we should clear it when stopping `SparkContext`, or all the future child threads will still inherit it and copy the properties and waste memory.
This is the root cause of https://issues.apache.org/jira/browse/SPARK-20548 , which creates/stops `SparkContext` many times and finally have a lot of `InheritableThreadLocal` alive, and cause OOM when starting new threads in the internal thread pools.

Closes#17800 from srowen/SPARK-20459.
There are two problems fixed in this commit. First, the
ExecutorAllocationManager sets a timeout to avoid requesting executors
too often. However, the timeout is always updated based on its value and
a timeout, not the current time. If the call is delayed by locking for
more than the ongoing scheduler timeout, the manager will request more
executors on every run. This seems to be the main cause of SPARK-20540.
The second problem is that the total number of requested executors is
not tracked by the CoarseGrainedSchedulerBackend. Instead, it calculates
the value based on the current status of 3 variables: the number of
known executors, the number of executors that have been killed, and the
number of pending executors. But, the number of pending executors is
never less than 0, even though there may be more known than requested.
When executors are killed and not replaced, this can cause the request
sent to YARN to be incorrect because there were too many executors due
to the scheduler's state being slightly out of date. This is fixed by tracking
the currently requested size explicitly.

The download link in history server UI is concatenated with:
```
<td><a href="{{uiroot}}/api/v1/applications/{{id}}/{{num}}/logs" class="btn btn-info btn-mini">Download</a></td>
```
Here `num` field represents number of attempts, this is not equal to REST APIs. In the REST API, if attempt id is not existed the URL should be `api/v1/applications/<id>/logs`, otherwise the URL should be `api/v1/applications/<id>/<attemptId>/logs`. Using `<num>` to represent `<attemptId>` will lead to the issue of "no such app".

Generate exec does not produce `null` values if the generator for the input row is empty and the generate operates in outer mode without join. This is caused by the fact that the `join=false` code path is different from the `join=true` code path, and that the `join=false` code path did deal with outer properly. This PR addresses this issue.

Currently, our project needs to be set to clean up the worker directory cleanup cycle is three days.
When I follow http://spark.apache.org/docs/latest/spark-standalone.html, configure the 'spark.worker.cleanup.appDataTtl' parameter, I configured to 3 * 24 * 3600.
When I start the spark service, the startup fails, and the worker log displays the error log as follows:
2017-04-28 15:02:03,306 INFO Utils: Successfully started service 'sparkWorker' on port 48728.

**Because we put 7 * 24 * 3600 as a string, forced to convert to the dragon type, will lead to problems in the program.**
**So I think the default value of the current configuration should be a specific long value, rather than 7 * 24 * 3600,should be 604800. Because it would mislead users for similar configurations, resulting in spark start failure.**

This PR proposes to fill up the documentation with examples for `bitwiseOR`, `bitwiseAND`, `bitwiseXOR`. `contains`, `asc` and `desc` in `Column` API.
Also, this PR fixes minor typos in the documentation and matches some of the contents between Scala doc and Python doc.
Lastly, this PR suggests to use `spark` rather than `sc` in doc tests in `Column` for Python documentation.

## What changes were proposed in this pull request?
It seems we are using `SQLUtils.getSQLDataType` for type string in structField. It looks we can replace this with `CatalystSqlParser.parseDataType`.
They look similar DDL-like type definitions as below:
```scala
scala> Seq(Tuple1(Tuple1("a"))).toDF.show()
```
```
+---+
| _1|
+---+
|[a]|
+---+
```
```scala
scala> Seq(Tuple1(Tuple1("a"))).toDF.select($"_1".cast("struct<_1:string>")).show()
```
```
+---+
| _1|
+---+
|[a]|
+---+
```
Such type strings looks identical when R’s one as below:
```R
> write.df(sql("SELECT named_struct('_1', 'a') as struct"), "/tmp/aa", "parquet")
> collect(read.df("/tmp/aa", "parquet", structType(structField("struct", "struct<_1:string>"))))
struct
1 a
```
R’s one is stricter because we are checking the types via regular expressions in R side ahead.
Actual logics there look a bit different but as we check it ahead in R side, it looks replacing it would not introduce (I think) no behaviour changes. To make this sure, the tests dedicated for it were added in SPARK-20105. (It looks `structField` is the only place that calls this method).
