This is a follow-up of #3367 and #3644.
At the time #3644 was written, #3367 hadn't been merged yet, thus `IsNull` and `IsNotNull` filters are not covered in the first version of `ParquetFilterSuite`. This PR adds corresponding test cases.

5974d10 [Yash Datta] SPARK-4968: takeOrdered to skip reduce step in case mappers return no partitions
Addition of a very limited number of local matrix manipulation and generation methods that would be helpful in the further development for algorithms on top of BlockMatrix (SPARK-3974), such as Randomized SVD, and Multi Model Training (SPARK-1486).
The proposed methods for addition are:
For `Matrix`
- map: maps the values in the matrix with a given function. Produces a new matrix.
- update: the values in the matrix are updated with a given function. Occurs in place.
Factory methods for `DenseMatrix`:
- *zeros: Generate a matrix consisting of zeros
- *ones: Generate a matrix consisting of ones
- *eye: Generate an identity matrix
- *rand: Generate a matrix consisting of i.i.d. uniform random numbers
- *randn: Generate a matrix consisting of i.i.d. gaussian random numbers
- *diag: Generate a diagonal matrix from a supplied vector
*These methods already exist in the factory methods for `Matrices`, however for cases where we require a `DenseMatrix`, you constantly have to add `.asInstanceOf[DenseMatrix]` everywhere, which makes the code "dirtier". I propose moving these functions to factory methods for `DenseMatrix` where the putput will be a `DenseMatrix` and the factory methods for `Matrices` will call these functions directly and output a generic `Matrix`.
Factory methods for `SparseMatrix`:
- speye: Identity matrix in sparse format. Saves a ton of memory when dimensions are large, especially in Multi Model Training, where each row requires being multiplied by a scalar.
- sprand: Generate a sparse matrix with a given density consisting of i.i.d. uniform random numbers.
- sprandn: Generate a sparse matrix with a given density consisting of i.i.d. gaussian random numbers.
- diag: Generate a diagonal matrix from a supplied vector, but is memory efficient, because it just stores the diagonal. Again, very helpful in Multi Model Training.
Factory methods for `Matrices`:
- Include all the factory methods given above, but return a generic `Matrix` rather than `SparseMatrix` or `DenseMatrix`.
- horzCat: Horizontally concatenate matrices to form one larger matrix. Very useful in both Multi Model Training, and for the repartitioning of BlockMatrix.
- vertCat: Vertically concatenate matrices to form one larger matrix. Very useful for the repartitioning of BlockMatrix.
The names for these methods were selected from MATLAB

This PR is another solution for When we build with sbt with profile for hadoop and without property for hadoop version like:
sbt/sbt -Phadoop-2.2 assembly
jar name is always used default version (1.0.4).
When we build with maven with same condition for sbt, default version for each profile is used.
For instance, if we build like:
mvn -Phadoop-2.2 package
jar name is used hadoop2.2.0 as a default version of hadoop-2.2.

It's really a minor issue.
In ApplicationMaster, there is code like as follows.
val preserveFiles = sparkConf.get("spark.yarn.preserve.staging.files", "false").toBoolean
I think, the code can be simplified like as follows.
val preserveFiles = sparkConf.getBoolean("spark.yarn.preserve.staging.files", false)

This PR modifies the python `SchemaRDD` to use `sample()` and `takeSample()` from Scala instead of the slower python implementations from `rdd.py`. This is worthwhile because the `Row`'s are already serialized as Java objects.
In order to use the faster `takeSample()`, a `takeSampleToPython()` method was implemented in `SchemaRDD.scala` following the pattern of `collectToPython()`.

Currently streaming block will be replicated when specific storage level is set, since WAL is already fault tolerant, so replication is needless and will hurt the throughput of streaming application.
Hi tdas , as per discussed about this issue, I fixed with this implementation, I'm not is this the way you want, would you mind taking a look at it? Thanks a lot.

Once the streaming receiver is de-registered at executor, the `ReceiverTrackerActor` needs to

SPARK-2261 uses a single file to log events for an app. `eventLogDir` in `ApplicationDescription` is replaced with `eventLogFile`. However, `ApplicationDescription` in `SparkDeploySchedulerBackend` is initialized with `SparkContext`'s `eventLogDir`. It is just the log directory, not the actual log file path. `Master.rebuildSparkUI` can not correctly rebuild a new SparkUI for the app.
Because the `ApplicationDescription` is remotely registered with `Master` and the app's id is then generated in `Master`, we can not get the app id in advance before registration. So the received description needs to be modified with correct `eventLogFile` value.

This PR tries to fix the Hive tests failure encountered in PR #3157 by cleaning `lib_managed` before building assembly jar against Hive 0.13.1 in `dev/run-tests`. Otherwise two sets of datanucleus jars would be left in `lib_managed` and may mess up class paths while executing Hive test suites. Please refer to [this thread] [1] for details. A clean build would be even safer, but we only clean `lib_managed` here to save build time.
This PR also takes the chance to clean up some minor typos and formatting issues in the comments.

Commit 7aacb7bfa added support for sharing downloaded files among multiple
executors of the same app. That works great in Yarn, since the app's directory
is cleaned up after the app is done.
But Spark standalone mode didn't do that, so the lock/cache files created
by that change were left around and could eventually fill up the disk hosting
/tmp.
To solve that, create app-specific directories under the local dirs when
launching executors. Multiple executors launched by the same Worker will
use the same app directories, so they should be able to share the downloaded
files. When the application finishes, a new message is sent to all workers
telling them the application has finished; once that message has been received,
and all executors registered for the application shut down, then those
directories will be cleaned up by the Worker.
Note: Unit testing this is hard (if even possible), since local-cluster mode
doesn't seem to leave the Master/Worker daemons running long enough after
`sc.stop()` is called for the clean up protocol to take effect.
