Demo on how to integrate Spring, Apache spark and GraphX, with Java and Scala mixed codes

The current project contains the following features:

• loading data from mariadb or mysql using spring-data-jpa
• spring boot support
• spark for big data analytics
• hadoop integration
• redis for publishing spark job progress
• graphx from graph mining such as page rank
• integration of both Java and Scala codes in a single code base

The application follows the following ETL flow:

• Step 1: data is extracted from mysql or mariadb database
• Step 2: data is transformed using spark
• Step 3: transformed data is then stored into into hadoop distributed file system (HDFS)
• Step 4: spark+graphx job is then run by load HDFS data into a graph structure and run graph mining
• Step 5: upon completion, the application automatically de-register itself from the chronos

To run this project, you need to create a database named my_sga in your mysql database (make sure it is running at localhost:3306)

CREATE DATABASE my_sga CHARACTER SET utf8 COLLATE utf8_unicode_ci;

Note that the default username and password for the mysql is configured to

• username: root
• password: chen0469

If your mysql or mariadb does not use these configuration, please change the settings in src/resources/config/application-default.properties

After the database is setup and configure, load the database demo data by unzipping my_sga.sql.zip and load the my_sga.sql into the my_sga database

To run this project, you must also have the following redis setup (as specified in the src/resources/config/application-default.properties):

mine.redis.hostports = localhost:6379
mine.redis.auth = chen0040

To run this project, you must also have the follow HDFS setup (as specified in the src/resources/config/application-default.properties)

mine.bigdata.hdfs.uri = hdfs://localhost:9000
mine.bigdata.hdfs.hadoop-username = chen0040

To run this project, you must also have the following mesos and chronos setup (as specified in the src/resources/config/application-default.properties):

mine.bigdata.chronos.url = http://localhost:4400
