- 2. PROPRIETARY & CONFIDENTIAL Web Analytics and Reporting Use Case ✦Hadoop ETL pipeline stitched together using hard-to-maintain, brittle scripts ✦Not enough personnel with expertise in all the Hadoop components (HDFS, MapReduce, Spark, YARN, HBase, Kafka) or lack of expertise ✦Hard to debug and validate, resulting in frequent failures in production environment Transform web log data from S3 every hour to Hadoop cluster for backup, as well as, perform analytics and enable realtime reporting of metrics such as number of successful/failure responses, most popular webpage etc. The Challenge —
- 3. PROPRIETARY & CONFIDENTIAL Demo Example Load Log Files from S3 to HDFS and perform aggregations/analysis •Start with web access logs stored in Amazon S3 •Store the raw logs into HDFS Avro Files •Parse the access log lines into individual fields •Calculate the total number of requests by IP and status code •Find out IPs which received maximum successful status code and error codes 69.181.160.120 - - [08/Feb/2015:04:36:40 +0000] "GET /ajax/planStatusHistory HTTP/1.1" 200 508 "http://builds.cask.co/log" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_1) AppleWebKit Chrome/38.0.2125.122 Safari/537.36" Fields: IP Address, Timestamp, Http Method, URI, Http Status, Response Size, URI, Client Info Sample Web access log (Combined Log Format):
- 4. PROPRIETARY & CONFIDENTIAL INGEST any data from any source in real-time and batch BUILD drag-and-drop ETL/ELT pipelines that run on Hadoop EGRESS any data to any destination in real-time and batch Data Pipeline provides the ability to automate complex workflows that involves fetching data, possibly from multiple data sources, combining, performing non-trivial transformations on the data, writing it to one more data sinks and deriving/
- 5. PROPRIETARY & CONFIDENTIAL Stack of Data Enablers
- 6. PROPRIETARY & CONFIDENTIAL Hydrator Studio ✦Drag-and-drop GUI for visual Data Pipeline creation ✦Rich library of pre-built sources, transforms, sinks for data ingestion and ETL use cases ✦Separation of pipeline creation from execution framework - MapReduce, Spark, Spark Streaming etc. ✦Hadoop-native and Hadoop Distro agnostic
- 7. PROPRIETARY & CONFIDENTIAL Hydrator Data Pipeline ✦ Captures Metadata, Audit, Lineage info and visualized using Cask Tracker ✦ Notification, centralized metrics and log collection for ease of operability ✦ Simple Java API to build your own source, transforms, sinks with complete class loading isolation ✦ SparkML based plugins, Python transforms for data scientists
- 8. PROPRIETARY & CONFIDENTIAL ✦ ElasticSearch, SFTP, Cassandra, Kafka, JMS and many more sources and sinks Out of the box Integrations
- 9. PROPRIETARY & CONFIDENTIAL ✦ Implement your own batch (or realtime) source, transform, sink plugins using simple Java API Custom Plugins
- 10. PROPRIETARY & CONFIDENTIAL Pipeline Implementation Logical Physical MR/Spark Executions Planner CDAP ✦ Planner converts logical pipeline to a physical execution plan ✦ Optimizes and bundles functions into one or more MR/Spark jobs ✦ CDAP is the runtime environment where all the components of the data pipeline are executed ✦ CDAP provides centralized log and metrics collection, transaction, lineage and audit information
