It has been observed that it offer some of the best benefits of the programmers as compared with any other framework. It makes it easy for programmers to write the code reliably and detect the same errors in same. It is purely based on Java and thus there are no compatibility issues. As far as the matter of functions and distribute systems is concerned, Hadoop has become the number one choice of several programmers all over the world. In addition to this, handling bulk data very easily is another good thing about this framework.[/vc_column_text][/vc_tta_section][vc_tta_section title=”What exactly do you know about the “Big Data” in the Hadoop?” tab_id=”1584461099208-8ae0d758-85d1″][vc_column_text]Relational database management tools often fail to perform their tasks and some stages. This is common when they have to handle a large amount of data. Big data is nothing but an array of complex data sets. It is actually an approach that makes it easy for businesses to get the maximum information from their data by properly searching, analyzing, sharing, transferring, capturing, as well as visualizing the same.[/vc_column_text][/vc_tta_section][vc_tta_section title=”Name the 5 Vs which are associated with the Hadoop Framework?” tab_id=”1584461100071-5728fae9-7d7e”][vc_column_text]These are:

Tell why they are significant.” tab_id=”1584461100790-1246f4c4-4d11″][vc_column_text]Hadoop is basically an approach that makes it easy for the users to handle big data without facing any problem. All the business decisions can simply be made by getting the most useful information in no time. Hadoop has been equipped with some of the best components that make it easy for the users to keep up the pace even if the data is too large. Hadoop has been equipped with two prime components and they are:

1. Processing Framework
2. Storage Unit[/vc_column_text][/vc_tta_section][vc_tta_section title=”Give abbreviation for YARN and HDFS” tab_id=”1584461101593-4ae5f7ed-948f”][vc_column_text]YARN stands for Yet Another Resource Negotiator
HDFS stands for Hadoop Distributed File System[/vc_column_text][/vc_tta_section][vc_tta_section title=”Where exactly the Data is stored in the Hadoop in a distributed environment? On what topology does it based on?” tab_id=”1584461102317-bf16c953-1050″][vc_column_text]Hadoop has a powerful data storage unit which is tagged as “Hadoop Distributed File System”. Any form of data can easily be stored in it in the form of blocks. It makes use of master and slave topology. In case the need of extended storage is felt, the same can be extended to fulfill the same. Hadoop is best in this aspect.[/vc_column_text][/vc_tta_section][vc_tta_section title=”What is name Name and Master Node in the Hadoop?” tab_id=”1584461112396-a8485dd6-8de2″][vc_column_text]These are actually related to storage in the Hadoop. Name Node is basically considered as a master node and is responsible for maintaining the Meta data information which is related to different blocks based on some of the factors related with them. Data Nodes are considered as Slave Nodes which is mainly responsible for storage and management of data in the basic format.[/vc_column_text][/vc_tta_section][/vc_tta_accordion][/vc_column][vc_column width=”1/2″][vc_tta_accordion color=”peacoc” active_section=”1″][vc_tta_section title=”Hadoop Security and Cluster Monitoring” tab_id=”1561382561432-7f73ef2a-cc67″][vc_column_text]

[/vc_column_text][/vc_tta_section][vc_tta_section title=”What exactly do you know about the Resource and Node Manager in the Hadoop Framework?” tab_id=”1584461103424-81f76eff-6d4c”][vc_column_text]Both Resource and Node Manager are associated with the YARN. Resource Manager is responsible for receiving the requests related to data processing. It then passes the same to the parallel Node Managers and ensures the processing has been taken place in a proper manner. On the other side Node Manager make sure the proper execution of task on every single Data Node.[/vc_column_text][/vc_tta_section][vc_tta_section title=”Which node is responsible for storing and modifying the FSImage in the Hadoop technology?” tab_id=”1584461104072-ac928246-bfb8″][vc_column_text]The Secondary Name Node is responsible for this. It generally performs this task with the help of other parallel nodes and make sure that the task has been processed at its level best. It also generated the reports related to same which are sent along with the data for the analysis of same in the step wise manner.[/vc_column_text][/vc_tta_section][vc_tta_section title=”What do you mean by NAS? Compare it with HDFS” tab_id=”1584461104780-159a1342-e38d”][vc_column_text]NAS stands for Network-attached Storage and is generally regarded as the storage server which is file-level. It is connected with a server and is mainly responsible to make sure that the access has been provided to a group of users. When it comes to storing and accessing the files, all the responsibilities are beard by the NAS which can be a software, or a hardware. On the other side, HDFS is a distributed file system and is actually based on commodity hardware.[/vc_column_text][/vc_tta_section][vc_tta_section title=”In the Hadoop technology, data can be stored in two different manners. Explain them and which one you prefer” tab_id=”1584461105429-e3292861-fcaa”][vc_column_text]Well, it is possible to store data in a distributed manner among all the machines within a cluster. Another approach is to choose a dedicated machine for the same. Distributed approach is a good option because failure of one machine doesn’t interrupt the entire functionality within an organization. Although back up can be created for the first case, accessing the backup data and bringing it into the main server can create a lot of time issues. Thus second option is a good one. It is reliable. However, all the machines within a cluster need to be protected in every aspect in case of confidential data or information.[/vc_column_text][/vc_tta_section][vc_tta_section title=” Can you compare HDFS and Relational Database Management System and bring some key differences?” tab_id=”1584461105981-f86f8035-0369″][vc_column_text]When it comes to Hadoop, it really doesn’t matter whether the data that needs to be stored is structured, unstructured or semi-structured. Also, the schema of data is totally unfamiliar to the Hadoop. On the other side, RDBMS always have structured data. It cannot process the others. The schema of same is always known to it. When it comes to processing capabilities, RDMS has limited number of options while Hadoop enables the same without any strict upper limit on the same. Another key difference is Hadoop is open source, while the RDBMS is licensed.[/vc_column_text][/vc_tta_section][vc_tta_section title=”When the Schema validation is done in the Hadoop approach?” tab_id=”1584461106693-a39e5a29-1bde”][vc_column_text]It is done mainly after the loading of the data. Sometime it even leads to bugs but that can be managed at a later stage. Actually, it follows the scheme on read protocol.[/vc_column_text][/vc_tta_section][vc_tta_section title=”For what purpose Hadoop is a good option to consider and Why?” tab_id=”1584461107315-676396e8-8eba”][vc_column_text]Hadoop is a good option to consider for OLAP systems, data discovery, as well as for Data Analysis. Hadoop has features that make the bulk data handling very easy. Because all these tasks have a lot of data to handle, the Hadoop approach can easily be trusted.[/vc_column_text][/vc_tta_section][/vc_tta_accordion][/vc_column][/vc_row]
