Summary: HBase is the Hadoop database. Use it when you need random, realtime read/write access to your Big Data. This project's goal is the hosting of very large tables -- billions of rows X millions of columns -- atop clusters of commodity hardware.

%description 
HBase is an open-source, distributed, column-oriented store modeled after Google' 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, HBase provides Bigtable-like capabilities on top of Hadoop. HBase includes:

    * Convenient base classes for backing Hadoop MapReduce jobs with HBase tables
    * Query predicate push down via server side scan and get filters
    * Optimizations for real time queries
    * A high performance Thrift gateway
    * A REST-ful Web service gateway that supports XML, Protobuf, and binary data encoding options
    * Cascading source and sink modules
    * Extensible jruby-based (JIRB) shell
    * Support for exporting metrics via the Hadoop metrics subsystem to files or Ganglia; or via JMX

%description thrift
ThriftServer - this class starts up a Thrift server which implements the Hbase API specified in the Hbase.thrift IDL file.
"Thrift is a software framework for scalable cross-language services development. It combines a powerful software stack with a code generation engine to build services that work efficiently and seamlessly between C++, Java, Python, PHP, and Ruby. Thrift was developed at Facebook, and we are now releasing it as open source." For additional information, see http://developers.facebook.com/thrift/. Facebook has announced their intent to migrate Thrift into Apache Incubator.
