Apache Hadoop is a framework for running applications on large clusters built of commodity hardware. The Hadoop framework transparently provides applications both reliability and data motion. Hadoop implements a computational paradigm named Map/Reduce, where the application is divided into many small fragments of work, each of which may be executed or reexecuted on any node in the cluster. In addition, it provides a distributed file system (HDFS) that stores data on the compute nodes, providing very high aggregate bandwidth across the cluster. Both Map/Reduce and the distributed file system are designed so that node failures are automatically handled by the framework.

Avro is a data serialization system. Avro provides: Rich data structures. A compact, fast, binary data format. A container file, to store persistent data. Remote procedure call (RPC). Simple integration with dynamic languages. Code generation is not required to read or write data files nor to use or implement RPC protocols. Code generation as an optional optimization, only worth implementing for statically typed languages.

Avro is a data serialization system. It is a subproject of Apache Hadoop.

JasperReports is the world's most popular open source reporting engine. It is entierly written in Java and it is able to use data coming from any kind of data source and produce pixel-perfect documents that can be viewed, printed or exported in a variety of document formats including HTML, PDF, Excel, OpenOffice and Word. JasperReports can use any data source provider, allowing it to extend reporting capabilities to almost any third-party application. When it is not possible to access data through JDBC, or when you do not want JasperReports to interact directly with a database, you can implement a custom JasperReports Data Source. In addition, any report can use data from multiple data sources, which can even be of different types. Its main feature includes
 <UL>
	<LI>Pixel-perfect page-oriented or continuous output for web or print </LI>
	<LI>Dashboards, tables, crosstabs, charts and gauges </LI>
	<LI>Report output in PDF, XML, HTML, CSV, XLS, RTF, TXT </LI>
	<LI>Multiple data sources of multiple kinds in one report</LI>

TagSoup, a SAX-compliant parser written in Java that, instead of parsing well-formed or valid XML, parses HTML as it is found in the wild: poor, nasty and brutish, though quite often far from short. TagSoup is designed for people who have to process this stuff using some semblance of a rational application design. TagSoup also includes a command-line processor that reads HTML files and can generate either clean HTML or well-formed XML that is a close approximation to XHTML.
