  • 69. All SQL on Hadoop Solutions are Missing the Point of Hadoop Every Solution makes you define a schema - SQL(Structured Query Language) is expressed over an assumed schema Major reasons why Hadoop has taken of include: - Ability to load data without defining a schema - Process data using schema-on-read instead of first defining a schema Hadoop contains a lot of: - Raw, granular data sets with potentially inconsistent schemas - Data sets in JSON, key-value, and other self-describing (non-relational) models designed for schema-on-read processing SQL on Hadoop solutions that make you first define a schema are missing a major part of Hadoop’s usage patterns Flexible Schema and the End of ETL http://strataconf.com/stratany2013/public/schedule/detail/31868
