Introduction to Apache Pig - GeeksforGeeks.
The program that we will be converting is contained in the file PigLatin.java. Lets take a look at this program and see how it solves the problem. main() The first thing to look at is the main(). It uses the following algorithm to read in a sentence of words and print out a pig latin equivalent. We will make use of an abstract idea know as a.
Hey, Iam trying to write a java application that acts as a one-word Pig Latin translator. The program should: 1.ask the user to enter a word. 2.convert the entered word into proper Pig Latin translation, (I have to use a method named translate to get the Pig Latin translation of the input word).
Pig Latin uses a lot fewer lines of code than the Java MapReduce script. The Pig Latin script was is easier to read for someone without a Java background. MapReduce jobs can written in Pig Latin. Java is a great and powerful language, but it has a higher learning curve than something like Pig Latin.
On our machine it took around 33 seconds with Pig using the Tez engine. That is nearly 3X faster than Pig using MapReduce even without any specific optimization in the script for Tez. Tez definitely lives up to it’s name. Further Reading. Welcome to Apache Pig! Pig Latin Basics; Programming Pig; Apache Tez.
Pydoop: It is a Python Module to write MapReduce programs using Python. It internally uses Hadoop Pipes. So It is Python wrapper over Hadoop Pipes. Pig: It offers a scripting like language called Pig Latin to analyse your data by performing a series of transformations and aggregations. Pig Latin is easy to learn and it is a data flow language.
Every task which can be achieved using PIG can also be achieved using java used in MapReduce. Features of Apache Pig. Let's see the various uses of Pig technology. 1) Ease of programming. Writing complex java programs for map reduce is quite tough for non-programmers. Pig makes this process easy. In the Pig, the queries are converted to.
Write an application that accepts a word from a user and converts it to Pig Latin. If a word starts with a consonant, the Pig Latin version removes all consonants from the beginning of the word and places them at the end, followed by ay. For example, cricket becomes icketcray. If a word starts with a vowel, the Pig Latin version is the original word with ay added to the end.
