The model trained by ALS requires partitioning information to do quick lookup of a user/item factor for making recommendation on individual requests. In the new implementation, we didn't set partitioners in the factors returned by ALS, which would cause performance regression.

DataFrame.explain return wrong result when the query is DDL command.
For example, the following two queries should print out the same execution plan, but it not.
sql("create table tb as select * from src where key > 490").explain(true)
sql("explain extended create table tb as select * from src where key > 490")
This is because DataFrame.explain leverage logicalPlan which had been forced executed, we should use the unexecuted plan queryExecution.logical.

`ReadContext.init` calls `InitContext.getMergedKeyValueMetadata`, which doesn't know how to merge conflicting user defined key-value metadata and throws exception. In our case, when dealing with different but compatible schemas, we have different Spark SQL schema JSON strings in different Parquet part-files, thus causes this problem. Reading similar Parquet files generated by Hive doesn't suffer from this issue.
In this PR, we manually merge the schemas before passing it to `ReadContext` to avoid the exception.

Fixes the issue whereby when VertexRDD's are `diff`ed, `innerJoin`ed, or `leftJoin`ed and have different partition sizes they fail under the `zipPartitions` method.

In Standalone mode, the number of cores in Completed Applications of the Master Web Page will always be zero, if sc.stop() is called.
But the number will always be right, if sc.stop() is not called.
The reason maybe:
after sc.stop() is called, the function removeExecutor of class ApplicationInfo will be called, thus reduce the variable coresGranted to zero. The variable coresGranted is used to display the number of Cores on the Web Page.

This is because the maven build generated two Jars-

2. a assembly JAR file containing everything in a different location as 1
The maven publishing plugin uploaded 1 and not 2.
Instead if 2 is not configure to generate in a different location, there is only 1 jar containing everything, which gets published.

**NOTICE** Do NOT merge this, as we're waiting for #3881 to be merged.
`HiveThriftServer2Suite` has been notorious for its flakiness for a while. This was mostly due to spawning and communicate with external server processes. This PR revamps this test suite for better robustness:
1. Fixes a racing condition occurred while using `tail -f` to check log file
It's possible that the line we are looking for has already been printed into the log file before we start the `tail -f` process. This PR uses `tail -n +0 -f` to ensure all lines are checked.
2. Retries up to 3 times if the server fails to start
In most of the cases, the server fails to start because of port conflict. This PR no longer asks the system to choose an available TCP port, but uses a random port first, and retries up to 3 times if the server fails to start.
3. A server instance is reused among all test cases within a single suite
The original `HiveThriftServer2Suite` is splitted into two test suites, `HiveThriftBinaryServerSuite` and `HiveThriftHttpServerSuite`. Each suite starts a `HiveThriftServer2` instance and reuses it for all of its test cases.
**TODO**
- [ ] Starts the Thrift server in foreground once #3881 is merged (adding `--foreground` flag to `spark-daemon.sh`)

Instead of storing a strong reference to accumulators, I've replaced this with a weak reference and updated any code that uses these accumulators to check whether the reference resolves before using the accumulator. A weak reference will be cleared when there is no longer an existing copy of the variable versus using a soft reference in which case accumulators would only be cleared when the GC explicitly ran out of memory.
