Dear BI Users: Your Hadoop SQL Wish Has Finally Come True

To accelerate the value of Big Data, many products have been developed to make data managed in Hadoop much easier to access and analyze through SQL.  First there was Hive, which provides a SQL query abstraction layer by converting SQL queries into MapReduce jobs.  More recently, Cloudera announced Impala which bypasses MapReduce to enable interactive queries on data stored in Hadoop using the same variant of SQL that Hive uses.  And today, EMC Greenplum announced Pivotal HD, the only high performing, true SQL query engine on top of Hadoop.  Don’t be confused by these approaches, as there is a common thread – to leverage Hadoop as a Big Data platform for running SQL queries.  The major difference with Pivotal HD is that now there is a single, scalable, flexible, and cost-effective data platform for all of your analytic needs.
