[ASTERIXDB-1992][ING] Suspend/Resume active entities - user model changes: wait for completion only returns when the entity becomes inactive. - storage format changes: no - interface changes: 01) Introduce: IMetadataLockManager for entity locking. IActiveNotificationHandler for handling active events. IRetryPolicy for recovery of failed active jobs. IActiveEntityController for controlling active entities. 02) IJobLifecycleListener.notifyJobFinish now passes the JobStatus and Exceptions. 03) IActiveEntityEventsListener.isActive() returns true, if entity is active, false otherwise. 04) IActiveEntityEventsListener.unregister() removes the listener upon entity deletion. 05) IActiveEntityEventsListener.getJobFailure() returns the job failure if the entity is in a failed state. 06) IStatementExecutor.getComponentProvider() returns the storage component provider. 07) IStatementExecutor.getApplicationContext() returns the application context. 08) IMetadataManager.upsertEntity to perfrom metadata entities' upsert operations. 09) IMetadataNode.upsertEntity to perfrom metadata entities' upsert operations 10) ICcApplicationContext.getMetadataLockManager() returns the lock manger. 11) ICcApplicationContext.getClusterStateManager() returns the cluster state manager. details: - Starting and stopping of active entities now go through their listeners rather than having the listener indicating active entity and not having it indicating inactive entity. This facilitates suspend/resume operations of long running active jobs for the sake of DDL operations or topology changes. - Unit tests for the vast majority of code paths and different possible scenarios have been added.

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

To build AsterixDB from source, you should have a platform with the following:
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
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/ $./opt/local/bin/start-sample-cluster.sh
Good to go and run queries in your browser at:
http://localhost:19001
