Pig Latin Statements. A Pig Latin statement is an operator that takes a relation as input and produces another relation as output. (This definition applies to all Pig Latin operators except LOAD and. STORE which read data from and write data to the file system.) Pig Latin statements can span multiple lines and must end with a

28 Feb 2012 Apache Pig changes this by creating a simpler procedural language abstraction over MapReduce to expose a more Structured Query Language (SQL)-like interface for Hadoop applications. So instead of writing a separate MapReduce application, you can write a single script in Pig Latin that is
Table 5-1 describes globs that are valid in Hadoop 0.20. Be aware that glob meaning is determined by HDFS underneath Pig, so the globs that will work for you depend on your version of HDFS. Also, if you are issuing Pig Latin commands from a Unix shell command line, you will need to escape many of the glob characters

What is Pig? Pig is a high level scripting language that is used with Apache Hadoop. Pig enables data workers to write complex data transformations without knowing Java. Pig's simple SQL-like scripting language is called Pig Latin, and appeals to developers already familiar with scripting languages and SQL. Pig is
A Pig relation is a bag of tuples. A Pig relation is similar to a table in a relational database, where the tuples in the bag correspond to the rows in a table. Unlike a relational table, however, Pig relations don't require that every tuple contain the same number of fields or that the fields in the same position (column) have the
26 Dec 2013 Apache Pig is a tool used to analyze large amounts of data by represeting them as data flows. Using the PigLatin scripting language operations like ETL (Extract, Transform and Load), adhoc data anlaysis and iterative processing can be easily achieved. Pig is an abstraction over MapReduce. In other
