Pivotal Hadoop Distribution and HAWQ Realtime Query Engine

SQL on Hadoop and the support for interactive, ad-hoc queries in Hadoop is in increasing demand and all the vendors are providing their answer to these requirements. In the open source world Cloudera’s Impala, Apache Drill (backed by MapR), Hortonworks’s Stinger initiatives are competing in this market, just to mention a few key players. There are also strong offerings from BI and analytics vendors such as Pivotal (HAWQ), Teradata (SQL-H) or IBM (BigSQL). In this post we will cover Pivotal Hadoop Distribution (Pivotal HD) and HAWQ, Pivotal’s interactive distributed SQL query engine.

Pivotal HD contains the most well-known open source components such as HDFS, MapReduce, YARN, Hive, Pig, HBase, Flume, Sqoop and Mahout. There are also additional components available such as the Command Center, Unified Storage Services, Data Loader, Spring and HAWQ as an add-on. (Pivotal has an offering called GemFire XD which is a distributed in-memory data grid but that is out of scope for our current discussion).
