Hadoop Application Architectures by
At its core, Hadoop is a distributed data store that provides a platform for implementing powerful parallel processing frameworks. The reliability of this data store when it comes to storing massive volumes of data, coupled with its flexibility in running multiple processing frameworks makes it an ideal choice for your data hub. This characteristic of Hadoop means that you can store any type of data as is, without placing any constraints on how that data is processed. A common term one hears in the context of Hadoop is Schema-on-Read. This simply refers to the fact that raw, unprocessed data can be loaded into Hadoop, with the structure imposed at processing time based on the requirements of the processing application. This is different from Schema-on-Write , which is generally used with traditional data management systems. Such systems require the schema of the data store to be defined before the data can be loaded.
MapReduce is a programming model and an associated implementation for processing and generating big data sets with a parallel , distributed algorithm on a cluster. A MapReduce program is composed of a map procedure , which performs filtering and sorting such as sorting students by first name into queues, one queue for each name , and a reduce method, which performs a summary operation such as counting the number of students in each queue, yielding name frequencies. The "MapReduce System" also called "infrastructure" or "framework" orchestrates the processing by marshalling the distributed servers, running the various tasks in parallel, managing all communications and data transfers between the various parts of the system, and providing for redundancy and fault tolerance. The model is a specialization of the split-apply-combine strategy for data analysis. As such, a single-threaded implementation of MapReduce is usually not faster than a traditional non-MapReduce implementation; any gains are usually only seen with multi-threaded implementations on multi-processor hardware. Optimizing the communication cost is essential to a good MapReduce algorithm.
What is Data Processing?
Apache Hadoop is an open source software framework used to develop data processing applications which are executed in a distributed computing environment. Commodity computers are cheap and widely available. These are mainly useful for achieving greater computational power at low cost.
With proper and effective use of Hadoop, you can build new-improved models, and based on that you will be able to make the right decisions. The first module, Hadoop beginners Guide will walk you through on understanding Hadoop with very detailed instructions and how to go about using it. The second module, Hadoop Real World Solutions Cookbook, 2nd edition, is an essential tutorial to effectively implement a big data warehouse in your business, where you get detailed practices on the latest technologies such as YARN and Spark.
Learning Deep Architectures for AI
Data processing is the collecting and manipulation of data into the usable and desired form. The manipulation is nothing but processing, which is carried either manually or automatically in a predefined sequence of operations. The next point is converting to the desired form, the collected data is processed and converted to the desired form according to the application requirements, that means converting the data into useful information which could use in the application to perform some task. The Input of the processing is the collection of data from different sources like text file data, excel file data, database, even unstructured data like images, audio clips, video clips, GPRS data, and so on. And the output of the data processing is meaningful information that could be in different forms like a table, image, charts, graph, vector file, audio and so all format obtained depending on the application or software required.
