Busting 10 Myths About Hadoop

Philip Russom clarifies some myths about Hadoop and MapReduce circulating inside the BI community:

  1. Hadoop consists of multiple products.
  2. Hadoop is open source but available from vendors, too.
  3. Hadoop is an ecosystem, not a single product.
  4. HDFS is a file system, not a database management system (DBMS).
  5. Hive resembles SQL but is not standard SQL.
  6. Hadoop and MapReduce are related but don’t require each other.
  7. MapReduce provides control for analytics, not analytics per se.
  8. Hadoop is about data diversity, not just data volume.
  9. Hadoop complements a DW; it’s rarely a replacement.
  10. Hadoop enables many types of analytics, not just Web analytics.

I do hope this lack of information and misconceptions are not real as otherwise some BI careers would really be endangered.
