Extract transformation load.
Hire is a datawarehouse system for Hadoop that facilitates easy data summarization, adhoc queries, and the analysis of large data sets stored in Hadoop compatible file systems.
Hire provides a mechanism to project structure onto this data and query the data using a SQL like language called Hire QL. At the same time this language also allows traditional map/reduce programers to plug in their custom mappers and reducers when it is inconvenient or inefficient to express by logic in HiveQL.
