In client side, the flow is SparkSubmit -> SparkContext -> yarn/Client. Since the yarn client only gets a cloned config and the staging dir is set here, it is not really possible to do re-logins in the SparkContext. So, do the initial logins in Spark Submit and do re-logins as we do now in the AM, but the Client behaves like an executor in this specific context and reads the credentials file to update the tokens. This way, even if the streaming context is started up from checkpoint - it is fine since we have logged in from SparkSubmit itself itself.

1. Remove the thread local `Accumulators.localAccums`. Instead, all Accumulators in the executors will register with its TaskContext.
2. Add an internal flag to Accumulable. For internal Accumulators, their updates will be sent to the driver via heartbeats.

**Symptom.** If an executor in an application times out, `HeartbeatReceiver` attempts to kill it. After this happens, however, the application never gets an executor back even when there are cluster resources available.
**Cause.** The issue is that `sc.killExecutor` automatically assumes that the application wishes to adjust its resource requirements permanently downwards. This is not the intention in `HeartbeatReceiver`, however, which simply wants a replacement for the expired executor.
**Fix.** Differentiate between the intention to kill and the intention to replace an executor with a fresh one. More details can be found in the commit message.

This pull request adds a Scalastyle regex rule which fails the style check if `Class.forName` is used directly. `Class.forName` always loads classes from the default / system classloader, but in a majority of cases, we should be using Spark's own `Utils.classForName` instead, which tries to load classes from the current thread's context classloader and falls back to the classloader which loaded Spark when the context classloader is not defined.

BlockObjectWriter has only one concrete non-test class, DiskBlockObjectWriter. In order to simplify the code in preparation for other refactorings, I think that we should remove this base class and have only DiskBlockObjectWriter.
While at one time we may have planned to have multiple BlockObjectWriter implementations, that doesn't seem to have happened, so the extra abstraction seems unnecessary.

This patch adds a cache-friendly external sorter which operates on serialized bytes and uses this sorter to implement a new sort operator for Spark SQL and DataFrames.
### Overview of the new sorter
The new sorter design is inspired by [Alphasort](http://research.microsoft.com/pubs/68249/alphasort.doc) and implements a key-prefix optimization in order to improve the cache friendliness of the sort. In naive sort implementations, the sorting algorithm operates on an array of record pointers. To compare two records for ordering, the sorter must dereference these pointers, which likely involves random memory access, then compare the objects themselves.
In a key-prefix sort, the sort operates on an array which stores the record pointer alongside a prefix of the record's key. When comparing two records for ordering, the sorter first compares the the stored key prefixes. If the ordering can be determined from the key prefixes (i.e. the prefixes are unequal), then the sort can avoid directly comparing the records, avoiding random memory accesses and full record comparisons. For example, if we're sorting a list of strings then we can store the first 8 bytes of the UTF-8 encoded string as the key-prefix and can perform unsigned byte-at-a-time comparisons to determine the ordering of strings based on their prefixes, only resorting to full comparisons for strings that share a common prefix. In cases where the sort key can fit entirely in the space allotted for the key prefix (e.g. the sorting key is an integer), we completely avoid direct record comparison.
In this patch's implementation of key-prefix sorting, our sorter's internal array stores a 64-bit long and 64-bit pointer for each record being sorted. The key prefixes are generated by the user when inserting records into the sorter, which uses a user-defined comparison function for comparing them. The `PrefixComparators` object implements a set of comparators for many common types, including primitive numeric types and UTF-8 strings.
The actual sorting is implemented by `UnsafeInMemorySorter`. Most consumers will not use this directly, but instead will use `UnsafeExternalSorter`, a class which implements a sort that can spill to disk in response to memory pressure. Internally, `UnsafeExternalSorter` creates `UnsafeInMemorySorters` to perform sorting and uses `UnsafeSortSpillReader/Writer` to spill and read back runs of sorted records and `UnsafeSortSpillMerger` to merge multiple sorted spills into a single sorted iterator. This external sorter integrates with Spark's existing ShuffleMemoryManager for controlling spilling.
Many parts of this sorter's design are based on / copied from the more specialized external sort implementation that I designed for the new UnsafeShuffleManager write path; see #5868 for more details on that patch.
### Sorting rows in Spark SQL
For now, `UnsafeExternalSorter` is only used by Spark SQL, which uses it to implement a new sort operator, `UnsafeExternalSort`. This sort operator uses a SQL-specific class called `UnsafeExternalRowSorter` that configures an `UnsafeExternalSorter` to use prefix generators and comparators that operate on rows encoded in the UnsafeRow format that was designed for Project Tungsten.
I used some interesting unit-testing techniques to test this patch's SQL-specific components. `UnsafeExternalSortSuite` uses the SQL random data generators introduced in #7176 to test the UnsafeSort operator with all atomic types both with and without nullability and in both ascending and descending sort orders. `PrefixComparatorsSuite` contains a cool use of ScalaCheck + ScalaTest's `GeneratorDrivenPropertyChecks` in order to test UTF8String prefix comparison.
### Misc. additional improvements made in this patch
This patch made several miscellaneous improvements to related code in Spark SQL:
- The logic for selecting physical sort operator implementations, which was partially duplicated in both `Exchange` and `SparkStrategies, has now been consolidated into a `getSortOperator()` helper function in `SparkStrategies`.
- The `SparkPlanTest` unit testing helper trait has been extended with new methods for comparing the output produced by two different physical plans. This makes it easy to write tests which assert that two physical operator implementations should produce the same output. I also added a method for disabling the implicit sorting of outputs prior to comparing them, a change which is necessary in order to be able to write proper SparkPlan tests for sort operators.
### Tasks deferred to followup patches
While most of this patch's features are reasonably well-tested and complete, there are a number of tasks that are intentionally being deferred to followup patches:
- Add tests which mock the ShuffleMemoryManager to check that memory pressure properly triggers spilling (there are examples of this type of test in #5868).
- Add tests to ensure that spill files are properly cleaned up after errors. I'd like to do this in the context of a patch which introduces more general metrics for ensuring proper cleanup of tasks' temporary files; see https://issues.apache.org/jira/browse/SPARK-8966 for more details.
- Metrics integration: there are some open questions regarding how to track / report spill metrics for non-shuffle operations, so I've deferred most of the IO / shuffle metrics integration for now.
- Performance profiling.

AFAIK, some spark application always use LocalBackend to do some local initiatives, spark sql is an example. Starting a LocalPoint won't add user classpath into executor.
```java
override def start() {
localEndpoint = SparkEnv.get.rpcEnv.setupEndpoint(
"LocalBackendEndpoint", new LocalEndpoint(SparkEnv.get.rpcEnv, scheduler, this, totalCores))
}
```
Thus will cause local executor fail with these scenarios, loading hadoop built-in native libraries, loading other user defined native libraries, loading user jars, reading s3 config from a site.xml file, etc

Currently, the mesos scheduler only looks at the 'cpu' and 'mem' resources when trying to determine the usablility of a resource offer from a mesos slave node. It may be preferable for the user to be able to ensure that the spark jobs are only started on a certain set of nodes (based on attributes).
For example, If the user sets a property, let's say `spark.mesos.constraints` is set to `tachyon=true;us-east-1=false`, then the resource offers will be checked to see if they meet both these constraints and only then will be accepted to start new executors.

Latest changes after refactoring to the RPC layer. I rebased against trunk to make sure to get any recent changes since it had been a while. I wasn't crazy about the name `ConfigureTimeout` and `RpcTimeout` seemed to fit better, but I'm open to suggestions!
I ran most of the tests and they pass, but others would get stuck with "WARN TaskSchedulerImpl: Initial job has not accepted any resources". I think its just my machine, so I'd though I would push what I have anyway.
Still left to do:
* I only added a couple unit tests so far, there are probably some more cases to test
* Make sure all uses require a `RpcTimeout`
* Right now, both the `ask` and `Await.result` use the same timeout, should we differentiate between these in the TimeoutException message?
* I wrapped `Await.result` in `RpcTimeout`, should we also wrap `Await.ready`?
* Proper scoping of classes and methods
hardmettle, feel free to help out with any of these!

The existing test suite has a lot of duplicate code and doesn't even cover the most fundamental feature of the HeartbeatReceiver, which is expiring hosts that have not responded in a while.
This introduces manual clocks in `HeartbeatReceiver` and makes it respond to heartbeats only for registered executors. A few internal messages are moved to `receiveAndReply` to increase determinism of the tests so we don't have to rely on flaky constructs like `eventually`.

If `fs.hdfs.impl.disable.cache` was `false`(default), `FileSystem` will use the cached `DFSClient` which use old token.
[AMDelegationTokenRenewer](https://github.com/apache/spark/blob/master/yarn/src/main/scala/org/apache/spark/deploy/yarn/AMDelegationTokenRenewer.scala#L196)
```scala
val credentials = UserGroupInformation.getCurrentUser.getCredentials
credentials.writeTokenStorageFile(tempTokenPath, discachedConfiguration)
```
Although the `credentials` had the new Token, but it still use the cached client and old token.
So It's better to set the `fs.hdfs.impl.disable.cache` as `true` to avoid token expired.

This issue was reported by saurfang. Thanks!
There is a following code in StagePage.scala.
```
|width="$serializationTimeProportion%"></rect>
|<rect class="getting-result-time-proportion"
|x="$gettingResultTimeProportionPos%" y="0px" height="26px"
|width="$gettingResultTimeProportion%"></rect></svg>',
|'start': new Date($launchTime),
|'end': new Date($finishTime)
|}
|""".stripMargin.replaceAll("\n", " ")
```
The last `replaceAll("\n", "")` doesn't work when we checkout and build source code on Windows and deploy on Linux.
It's because when we checkout the source code on Windows, new-line-code is replaced with `"\r\n"` and `replaceAll("\n", "")` replaces only `"\n"`.

17fb044 [Kousuke Saruta] Fixed a new-line-code issue
Because `System.currentTimeMillis()` is not accurate for tasks that only need several milliseconds, sometimes `totalExecutionTime` in `makeTimeline` will be 0. If `totalExecutionTime` is 0, there will the following error in the console.
This PR fixes it by using an empty svg tag when `totalExecutionTime` is 0. This is a screenshot for a task that its totalExecutionTime is 0 after fixing it.

Showing these applications may lead to weird behavior in the History Server. For old logs, if
the app ID is recorded later, you may end up with a duplicate entry. For new logs, the app might
be listed with a ".inprogress" suffix.
So ignore those, but still allow old applications that don't record app IDs at all (1.0 and 1.1) to be shown.

Subset the enabled algorithms in an SSLOptions to the elements that are supported by the protocol provider.
Update the list of ciphers in the sample config to include modern algorithms, and specify both Oracle and IBM names. In practice the user would either specify their own chosen cipher suites, or specify none, and delegate the decision to the provider.

This is a simple change to add a new environment variable
"spark.sparkr.r.command" that specifies the command that SparkR will
use when creating an R engine process. If this is not specified,
"Rscript" will be used by default.
I did not add any documentation, since I couldn't find any place where
environment variables (such as "spark.sparkr.use.daemon") are
documented.
I also did not add a unit test. The only test that would work
generally would be one starting SparkR with
sparkR.init(sparkEnvir=list(spark.sparkr.r.command="Rscript")), just
using the default value. I think that this is a low-risk change.
