This patch builds upon #5694 to add a 'module' abstraction to the `dev/run-tests` script which groups together the per-module test logic, including the mapping from file paths to modules, the mapping from modules to test goals and build profiles, and the dependencies / relationships between modules. This refactoring makes it much easier to increase the granularity of test modules, which will let us skip even more tests. It's also a prerequisite for other changes that will reduce test time, such as running subsets of the Python tests based on which files / modules have changed. This patch also adds doctests for the new graph traversal / change mapping code.

**Summary of the problem in SPARK-8470.** When using `HiveContext` to create a data frame of a user case class, Spark throws `scala.reflect.internal.MissingRequirementError` when it tries to infer the schema using reflection. This is caused by `HiveContext` silently overwriting the context class loader containing the user classes. **What this issue is about.** This issue adds regression tests for SPARK-8470, which is already fixed in #6891. We closed SPARK-8470 as a duplicate because it is a different manifestation of the same problem in SPARK-8368. Due to the complexity of the reproduction, this requires us to pre-package a special test jar and include it in the Spark project itself. I tested this with and without the fix in #6891 and verified that it passes only if the fix is present.

In earlier versions of Spark SQL we casted `TimestampType` and `DataType` to `StringType` when it was involved in a binary comparison with a `StringType`. This allowed comparing a timestamp with a partial date as a user would expect. - `time > "2014-06-10"` - `time > "2014"` In 1.4.0 we tried to cast the String instead into a Timestamp. However, since partial dates are not a valid complete timestamp this results in `null` which results in the tuple being filtered. This PR restores the earlier behavior. Note that we still special case equality so that these comparisons are not affected by not printing zeros for subsecond precision.

tdas zsxwing this is the new PR for Spark-8080 I have merged https://github.com/apache/spark/pull/6659 Also to mention , for MEMORY_ONLY settings , when Block is not able to unrollSafely to memory if enough space is not there, BlockManager won't try to put the block and ReceivedBlockHandler will throw SparkException as it could not find the block id in PutResult. Thus number of records in block won't be counted if Block failed to unroll in memory. Which is fine. For MEMORY_DISK settings , if BlockManager not able to unroll block to memory, block will still get deseralized to Disk. Same for WAL based store. So for those cases ( storage level = memory + disk ) number of records will be counted even though the block not able to unroll to memory. thus I added the isFullyConsumed in the CountingIterator but have not used it as such case will never happen that block not fully consumed and ReceivedBlockHandler still get the block ID. I have added few test cases to cover those block unrolling scenarios also.
