Apache Pig===========Pig is a dataflow programming environment for processing very large files. Pig'slanguage is called Pig Latin. A Pig Latin program consists of a directedacyclic graph where each node represents an operation that transforms data.Operations are of two flavors: (1) relational-algebra style operations such asjoin, filter, project; (2) functional-programming style operators such as map,reduce. Pig compiles these dataflow programs into (sequences of) map-reduce or Apache Tezjobs and executes them using Hadoop. It is also possible to execute Pig Latinprograms in a "local" mode (without Hadoop cluster), in which case all processing takes place in a single local JVM.
