The Hadoop ecosystem is the leading opensource platform for distributed storage and processing of "big data". The Hadoop platform is available at CERN as a central service provided by the IT department.
Real-time data ingestion to Hadoop ecosystem due to the system specificity is non-trivial process and requires some efforts (which is often underestimated) in order to make it efficient (low latency, optimize data placement, footprint on the cluster).
In this tutorial attendees will learn about:
