Acutally spark sql will first go through analysis period, in which we do widen types and promote strings, and then optimization, where constant IN will be converted into INSET.

So it turn out that we only need to fix this for IN.

This patch adds a one hot encoder for categorical features.  Planning to add documentation and another test after getting feedback on the approach.

A couple choices made here:
* There's an `includeFirst` option which, if false, creates numCategories - 1 columns and, if true, creates numCategories columns.  The default is true, which is the behavior in scikit-learn.
* The user is expected to pass a `Seq` of category names when instantiating a `OneHotEncoder`.  These can be easily gotten from a `StringIndexer`.  The names are used for the output column names, which take the form colName_categoryName.

[SPARK-5074] [CORE] [TESTS] Fix the flakey test 'run shuffle with map stage failure' in DAGSchedulerSuite

Test failure: https://amplab.cs.berkeley.edu/jenkins/job/Spark-Master-SBT/AMPLAB_JENKINS_BUILD_PROFILE=hadoop2.2,label=centos/2240/testReport/junit/org.apache.spark.scheduler/DAGSchedulerSuite/run_shuffle_with_map_stage_failure/

This is because many tests share the same `JobListener`. Because after each test, `scheduler` isn't stopped. So actually it's still running. When running the test `run shuffle with map stage failure`, some previous test may trigger [ResubmitFailedStages](https://github.com/apache/spark/blob/ebc25a4ddfe07a67668217cec59893bc3b8cf730/core/src/main/scala/org/apache/spark/scheduler/DAGScheduler.scala#L1120) logic, and report `jobFailed` and override the global `failure` variable.

This PR uses `after` to call `scheduler.stop()` for each test.

* Uses jersey + jackson for routing & converting POJOs into json
* tests against known results in `HistoryServerSuite`
* also fixes some minor issues w/ the UI -- synchronizing on access to `StorageListener` & `StorageStatusListener`, and fixing some inconsistencies w/ the way we handle retained jobs & stages.

7d6153a [Jihong MA] SPARK-7357 Improving HBaseTest example

"The best way to size the amount of memory consumption your dataset will require is to create an RDD, put it into cache, and look at the SparkContext logs on your driver program. The logs will tell you how much memory each partition is consuming, which you can aggregate to get the total size of the RDD."
-the Tuning Spark page

This is a pain. It would be much nicer to expose simply functionality for understanding the memory footprint of a Java object.

Without this, any dependency that pulls ivy transitively may override
the version and potentially cause issue. In my machine, the hive tests
were pulling an old version of ivy, and subsequently failing with a
"NoSuchMethodError".

[MINOR] Renamed variables in SparkKMeans.scala, LocalKMeans.scala and kmeans.py to simplify readability

With the previous syntax it could look like that the reduceByKey sums separately abscissas and ordinates of some 2D points. Perhaps in this way should be easier to understand the example, especially for who is starting the functional programming like me now.
