The Apache Hadoop project develops open-source software for reliable, scalable, distributed computing, including:
* Hadoop Core, our flagship sub-project, provides a distributed filesystem (HDFS) and support for the MapReduce distributed computing framework.
* HBase builds on Hadoop Core to provide a scalable, distributed database.
* Pig is a high-level data-flow language and execution framework for parallel computation. It is built on top of Hadoop Core.
* ZooKeeper is a highly available and reliable coordination system. Distributed applications use ZooKeeper to store and mediate updates for critical shared state.
* Hive is a data warehouse infrastructure built on Hadoop Core that provides data summarization, adhoc querying and analysis of datasets.
The National Digital Newspaper Program (NDNP), a partnership between the National Endowment for the Humanities (NEH) and the Library of Congress (LC), is a long-term effort to develop an Internet-based, searchable database of all U.S. newspapers with descriptive information and select digitization of historic pages. Supported by NEH, this rich digital resource will be developed and permanently maintained at the Library of Congress. An NEH grant program will fund the contribution of content from, eventually, all U.S. states and territories.
Welcome! This is the main page for Biglumber, a site designed to help people sign each other's OpenPGP keys, by looking up cities around the world. Signing keys allows you to expand your web of trust, a very important part of using public key cryptography. Keys are not listed here until it has been verified that the email address for the key is valid and belongs to the owner of the key.
