Apache Hive: 5 facts

  1. Hive is a SQL-like layer on top of Hadoop
  2. Use it when you have some sort of structure to your data.
  3. You can use JDBC and ODBC drivers to interface with your traditional systems. However, it’s not high performance.
  4. Originally built by (and still used by) Facebook to bring traditional database concepts into Hadoop in order to perform analytics. Also used by Netflix to run daily summaries.
  5. Pig is sometimes compared to Hive, in that they are both “languages” that are layered on top of Hadoop. However, Pig is more analogous to a procedural language to write applications, while Hive is targeted at traditional DB programmers moving over to Hadoop.
