Subject Re: Implementing join on hadoop

Hi Miryala,

In general you should use core-user@hadoop.apache.org (subscribe here: http://hadoop.apache.org/core/mailing_lists.html)

  for questions about using Hadoop. Anyway, joins and other SQL  
operators are implemented by both the Hive and Pig Hadoop sub-projects  
(linked at the top of http://hadoop.apache.org/) and by the DataJoin  
library in Hadoop. Hive is the closest thing to a relational database  
on Hadoop, supporting table schemas, a centralized metadata  
repository, and a SQL-like query language. Pig is a high-level  
language for writing Hadoop workflows that includes SQL operators.
