Best Hadoop training institutes in Hyderabad,

Hadoop course structor and eco systems by RStrainings
Now we are living in Big data world. Today, the amount of unstructured data getting added to warehouse from different sources got increased exponentially. So the challenge is how to get the business value or customer insights out of this huge raw data. One of the most popular technology that is aiming to solve this big data related analytics is HADOOP. Hadoop is an open-source framework,RStrainings is best training center in hyderabad for hadoop training which is written in Java on Linux Operating System, which is intended to resolve the Big Data related to issues in terms of Storage wise and Processing wise. Hadoop is developed on a few important ideas and It is very rich in its features. First, It uses commodity machines to store its raw data.Second,code-locality. Moving the code where data resides over the network from one machine to another machine.This process is more efficient and faster processing methodology to handle very large datasets.Third, fault tolerance by having more copies within the cluster for high data availability and handles the system failure, Rstrainings providing Hadooop training in classroom and online
Hadoop framework uses mainly its two core components to store and process the Big Data[large] datasets. One is HDFS, Hadoop distributed File System, and another one is MapReduce. 
Same as Linux, the HDFS will split/divide/partition the entire data into chunks of data(each chunk will be called as Block size in Hadoop) and distribute them across multiple servers within Hadoop Cluster. MapReduce is a programming language and which helps to process the large datasets stored in HDFS.RStrainings is providing every session practically and understandble examples..
The Hadoop cluster consists of two types of nodes[Individual machines]: Master Node and WorkerNode. Always MasterNodes manages something within cluster and Hadoop Cluster can have more than one MasterNode. NameNode is MasterNode which manages the entire MetaData of its cluster. So it is counter-piece/heart of Hadoop cluster. A WorkerNode(can be called Data Node) stores the actual file in the form of Blocks.Whenever client wants to read or write into HDFS, first it contacts a NameNode. So If NameNode crashes/doesn't work then the entire hadoop cluster becomes inaccessible.RStrainings providing training world wide like usa, india , Singpore,Malasia, UK, CANADA etc..
Different Hadoop Eco-Components:-
PIG:- Pig is a base platform,developed by yahoo in 2006,high level data-flow language, which provides alternative abstraction on top of MapReduce program. It uses its own scripting language called Pig Latin. The Pig framework translate the Pig Latin scripts into series of MapReduce programs. RStrainings was located in Madhapur pin code is 500081
Hive:-Hive is data warehouse infrastructure software. It is both, a storage component where It stores the underlined data in HDFS and also a processing Component where it can analyze the Big Data stored in HDFS. Hive provides a SQL-like query language called HQL(Hive Query Language(HiveQL)).
HBASE:-Using RDBMS doesn't scale well and its is hard to shard the data. Hbase is another hadoop distributed column oriented ecosystem. It is also a database which built on top of HDFS. HBASE does not use the MapReduce programming to process the Big data. Unlike MapReduce program,Hbase can access the data randomly where online meets low-latency.

Is java essential to learn Hadoop?

Is java essential to learn Hadoop?          As we all know that Hadoop is built in java. So, basics of java are used at some sectors in Hadoop. It doesn't mean that you should definitely have the complete knowledge regarding java in depth. There are many other concepts in Hadoop you can learn without the help of java, In Hadoop java is used to code on MapReduce.
                  Although you are not good at java programming but have good skills at SQL can also learn Hadoop. There are some concepts like:-
1. pig
1) pig
"pig is a high-level data flow language"
"It is a beheading framework for parallel         computation"
 "It is generally used by programmers and researchers"
2) Hive
"Hive provides ad-hoc querying and data summarization"
"It is a data warehouse infrastructure"
"It is mostly used by data analysts"
                             you can only need to learn pig latin and Hive SQL (HQL) in Hadoop. Both only needs SQL base. HQL is same as SQL that takes queries and changes them into MapReduce jobs.HQL is faster and permissive feature of SQL.
  • These two concepts are very easy to learn.                                   
  •  More than 80% of the Hadoop projects are depending on pig and hive.

Hadoop and Big Data Over View

Hadoop is a free open-source software framework for storing data and running applications on clusters of commodity hardware. It provides all-powerful storage for any nice of data, omnipotent supervision power and the doing to handle just about limitless concurrent tasks or jobs.
How Is Hadoop Being Used?
Going far away and wide ahead than its indigenous mean of searching millions (or billions) of web pages and returningrelevant results, many organizations are looking to Hadoop as their neighboring-door gigantic data platform. Popular uses today include:

1.Low-cost storage and data archive   

2.Sandbox for discovery and analysis        

3.Data lake        

 4.Complement your data warehouse 

 5.IoT and Hadoop

Hadoop is a easy to get praise of to, Java-based programming framework that supports the paperwork of large data sets in a distributed computing setting. It is share of the apache project sponsored by the Apache Software Foundation.                                                                                         Hadoop makes it realizable to run applications harshly speaking systems gone thousands of nodes involving thousands of terabytes. Its distributed file system facilitates trenchant data transfer rates together along in the company allows the system to continue operating uninterrupted in deed of a node failure. This associations  the risk of catastrophic system failure, though a significant number of nodes become inoperative.  Hadoop was inspired by Google's MapReduce and software framework in which an application is blinking beside into numerous little parts. Any of these parts (furthermore known as fragments or blocks) can be counsel in version to any node in the cluster. Doug Cutting, Hadoop's creator and named the framework after his child's stuffed toy elephant. The current Apache Hadoop eco system consists of the Hadoop kernel Map Reduce the Hadoop distributed file system (HDFS) and a number of associated projects such as Apache Hive, HBase and Zookeeper.            

The Hadoop is framework used by major players including Google, Yahoo and IBM, largely for applications involving search engines and advertising. The operating systems are Windows and Linux but Hadoop can moreover undertaking subsequent to BSD and OS X.
