Apache Hadoop open source technology is today the data management platform most related to the analysis of large amounts of information. Therefore, there are many developers and IT experts who want to learn how to handle it properly. The future has become present. The moment in which the analysis of big data is crucial in many companies around the world has stopped being “tomorrow”, to become ” now”.
The origin of this processing framework goes back a little over a decade in time. In 2006, Hadoop became a reality, due to the needs that were already foreseen in the near future. Yahoo was the first company that applied the functionalities of what is now Apache Hadoop to analyze big data. But soon other important companies such as Facebook, LinkedIn and Twitter joined them. These and many others adopted Hadoop technology and began to contribute to its development.
In this way, in recent times, Hadoop has become a complex ecosystem of infrastructure components and related tools, already used by countless companies around the world. And it is not for less, since what Hadoop offers in the world of IT and big data analysis is very powerful. Great performance at low cost, more than meeting the expectations of advanced data analytics.
Thus, Hadoop is no longer synonymous exclusively with the large and millionaire companies mentioned above, but its use has been extended to other industries. For example, some of its functionalities at present are the preparation and generation of reports, or the presentation and analysis of unstructured, semi-structured and structured data. Is it just the great Facebook or the superb LinkedIn interested in knowing information about the clicks on its website, its online advertising, or data provided by the sensors in the factories or other devices of the internet of things? Of course not.
Who manages the Hadoop big data management environment?
But who is capable of handling this powerful technology? Who is responsible for manipulating and understanding all this volume of analyzed data? An architecture expert from YARN, Spark, HDFS, Impala, Kudu, HBase, Solr and other tools of the Hadoop ecosystem. Someone capable of loading data in the cluster from files generated dynamically by Flume and from RDBMS using Sqoop. Someone who knows troubleshooting, diagnosis, tinning and problem solving in Hadoop. All this and much more, integrated in a single person. Namely, we are talking only, of an Apache Hadoop administrator.
We must bear in mind that this technology only expresses all its possibilities if there is someone behind it, human and not a machine, who is able to reach where robots cannot. Here is the tremendous market gap of the near future, almost the immediate present. But, how do you become an Apache Hadoop administrator? How are you able to carry out all the functions described above? The most professional way to achieve this is through our Apache Hadoop administrator for Cloudera course. With basic knowledge, interest, motivation and great involvement, those who successfully complete this training will achieve one of the most successful certifications in the market: The Cloudera Administrator certification in Apache Hadoop.
What does a Hadoop administrator do in his day-to-day?
Hadoop is responsible for analyzing large amounts of data, yes. But a Hadoop administrator must make the yield of this technology the desired one for the company that wants to use it. For this, it is necessary to carry out planning, designs and development of operations that, in the form of tests, guarantee an optimal performance of the tool.
In this sense, some of the most common and demanded profiles related to the Apache Hadoop administration are those that we quote below. On the one hand, it is necessary to have requirement analysts who are responsible for evaluating the performance of the system taking into account the different applications that will be executed in the Hadoop environment.
It is also very important the role of system architects, who focus on the design hardware, or that of the systems engineers, who are the ones who install and configure the Hadoop software properly.
In addition, when working in environments where Hadoop is the protagonist, companies also tend to search for application developers, data management professionals, system administrators and project managers. Any of these positions can be chosen by someone who, after completing the Apache Hadoop administrator course of Cloudera, has managed to obtain the pertinent certification.
Hadoop in the company
We have already mentioned that Hadoop was first used in Yahoo, and continued its trajectory in other big companies. To those mentioned above we can add others such as Google, eBay, AOL, Adobe or IBM. But don’t let the popularity of these big companies deceive you.
Hadoop is also designed for companies that are not so giant but equally ambitious, who wish to have the power of information. Or for factories and industries that want to use the internet of things. And is that this framework enjoys great popularity in the business sector. This is because it is possible to implement clusters for the processing of large amounts of data with standard computers with hadoop. In addition, other highly valued features of this open source software are its stability, its expansion options and the large number of functions that its users can access.
Hadoop y Cloudera, hand in hand
It should be noted that the developer Doug Cutting was the creator of this technology based on analyzing large amounts of data with the help of clusters. An idea, by the way, inspired by the Google MapReduce algorithm. And where can we find Cutting today, thirteen years later? Precisely in Cloudera. Therefore, the course of administrator in Apache Hadoop of Cloudera is presented as the ideal option to acquire the necessary knowledge required to master this technology.
Cloudera Apache Hadoop course at PUE, your EMEA Best Training Partner
At PUE we offer the possibility of taking the course of administrator of Apache Hadoop of Cloudera to all the people interested in training in this environment. To be able to do it, it is necessary that the students have a basic level of previous knowledge in the administration of Linux systems. However, it is not a requirement to know Hadoop before you start.
The Apache Hadoop administrator course for Cloudera is aimed at those responsible for the management of Apache Hadoop clusters and system administrators who work or want to work in Hadoop environments.
IT experts around the world already predict it: the future of professions is in technology and, specifically, in big data. And being able to handle this type of frameworks offers opportunities to access jobs where there is currently more demand than specialized profiles.
