Four steps to Analytics on Hadoop
Start by creating a Stream.
bin/cdap-cli.sh "create stream logEventStream"
Then, load some data into the Stream
bin/cdap-cli.sh "load stream logEventStream examples/resources/accesslog.txt"Now that you have loaded data into Stream, you can run HIVE SQL queries to explore the data. You can find more information here.
Process ingested weblogs to generate analytics using the ETL Batch Adapter and store in OLAP Cube Dataset.
bin/cdap-cli.sh -s examples/resources/weblog-adapter.txtFind out more about Application Templates and ETL Adapters here. Take a look at the CLI script below for details.
Analytics generated in the previous step can be served using HTTP Service.
bin/cdap-cli.sh -s examples/resources/weblog-service.txt
Query the cube results (Note: Workflow triggers every 1 min)
bin/cdap-cli.sh -s examples/resources/weblog-query.txt
Try configuring the same through CDAP UI
Now that you have set up and understand CDAP, here is some more information to help you experience it more deeply!
