Supports flexible degree of parallelism.

Detailed list of changes include:
- Add the IClusterInfoCollector interface and feed that to the compiler;
- Add the number of cores into the heartbeat;
- Add partition calculation in APIFramework;
- Fix partitioning property requirements in binary operators such as Join and UnionAll;
- Fix PushSubplanIntoGroupByRule for type propagation;
- Fix InlineLeftNtsInSubplanJoinFlatteningVisitor for the returned top join operator;
- Add unit test for partition calculation in APIFrameworkTest
- Add integration test SqlppExecutionFullParallelismIT, SqlppExecutionLessParallelismIT,
  AqlExecutionFullParallelismIT, and AqlExecutionLessParallelismIT for different
  parallelism settings;
- Refactor AQLExecutionTest and SqlppExecutionTest;
- Separate one cluster state test out from AqlExecutionTest.

#AsterixDB

AsterixDB is a BDMS (Big Data Management System) with a rich feature set that sets it apart from other Big Data platforms. Its feature set makes it well-suited to modern needs such as web data warehousing and social data storage and analysis. AsterixDB has:

A semistructured NoSQL style data model (ADM) resulting from extending JSON with object database ideas
Two expressive and declarative query languages (SQL++ and AQL) that support a broad range of queries and analysis over semistructured data
A parallel runtime query execution engine, Apache Hyracks, that has been scale-tested on up to 1000+ cores and 500+ disks
Partitioned LSM-based data storage and indexing to support efficient ingestion and management of semistructured data
Support for query access to externally stored data (e.g., data in HDFS) as well as to data stored natively by AsterixDB
A rich set of primitive data types, including spatial and temporal data in addition to integer, floating point, and textual data
Secondary indexing options that include B+ trees, R trees, and inverted keyword (exact and fuzzy) index types
Support for fuzzy and spatial queries as well as for more traditional parametric queries
Basic transactional (concurrency and recovery) capabilities akin to those of a NoSQL store

##Building AsterixDB

To build AsterixDB from source, you should have a platform with the following:

A Unix-ish environment (Linux, OS X, will all do).
git
Maven 3.3.9 or newer.
Java 8 or newer.

Instructions for building the master:

Checkout AsterixDB master:

  $git clone https://github.com/apache/asterixdb.git

Build AsterixDB master:

  $cd asterixdb
  $mvn clean package -DskipTests

##Running AsterixDB (on your machine from your build) Here are steps to get AsterixDB running on your local machine:

Start a single-machine AsterixDB instance:

  $cd asterixdb/asterix-server/target/asterix-server-*-binary-assembly/
  $./samples/local/bin/start-sample-cluster.sh

Good to go and run queries in your browser at:
```
  http://localhost:19001
```
Read more documentations to learn the data model, query language, and how to create a cluster instance: [https://ci.apache.org/projects/asterixdb/index.html] (https://ci.apache.org/projects/asterixdb/index.html)

##Documentation

AsterixDB's official documentation resides at [https://ci.apache.org/projects/asterixdb/index.html] (https://ci.apache.org/projects/asterixdb/index.html). This is built from the maven project under asterix-doc/ as a maven site. The documentation on the official website refers to the most stable build version, so for pre-release versions one should refer to the compiled documentation.
