In this session we will take a deep dive into Hadoop, HDFS and MapReduce internals from an Oracle Database administrator’s or developer’s perspective. We will explore the similarities and differences between a Parallel Query running on an Oracle RAC Database and a MapReduce job running on a Hadoop Cluster.
This is not a high-level session talking about general possibilities of using Hadoop, but a detailed look into Hadoop parallel processing and IO flow.
