Detailed Description

Apache HBase is used when you need random, realtime read/write access to your Big Data. Apache HBase hosts very large tables -- billions of rows X millions of columns -- atop clusters of commodity hardware. Apache HBase is a distributed, versioned, non-relational database modeled after Google's Bigtable: A Distributed Storage System for Structured Data by Chang et al. Just as Bigtable leverages the distributed data storage provided by the Google File System, Apache HBase provides Bigtable-like capabilities on top of Hadoop and HDFS.

Benefit to Fedora

Apache HBase is the Big Data database used by many parts of the Hadoop Ecosystem. Including it in Fedora increases usefulness of the Apache Hadoop that is already in Fedora.
