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 to get the business value or customer insights out of this raw data. One of the most popular technology that is aiming to solve the big data related analytics is HADOOP. Hadoop Training in India Hadoop is an open-source framework, 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

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.Hadoop Training in Hyderabad
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.

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.Hadoop Training institutes in Hyderabad 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.

Hadoop is a best process for companies and organization ... Some large companies are moving on hadoop now is hadoop with spark and scala is more advantages and impressive..best carrier wise hadoop is way of path for correct way ..main components in scala is special in bigdata...
in world wide mostmnc cmpanies are using hadoop technologies..
