This technical tutorial will go over the fundamentals of Hadoop: its distributed filesystem (HDFS) and processing engine (MapReduce), as well as looking at higher-level tools for data analytics (Pig and Hive). Plenty of code examples will be provided throughout. The following areas will be covered:
Moving data into HDFS.
Writing a simple MapReduce job.
Tips for writing advanced MapReduce jobs.
An introduction to Pig Latin.
Writing Hive queries.
