The Big Data and Hadoop Training course from Maxonlinetraing is specially designed in such a way that everyone can enhance their knowledge and skills to become a successful Hadoop developer.
About The Hadoop Admin Online Training:
Maxonlinetraining.com Big Data Hadoop Administrator online training course is mainly intended to understand the core concepts of Apache Hadoop and Hadoop Cluster mainly. It covers the important concepts associated to secure a Hadoop Cluster and Hbase administration.
Course content: 1. Hadoop Cluster Administration 2. Hadoop Architecture and Cluster setup 3. Hadoop Cluster: Planning and Managing 4. Backup, Recovery and Maintenance 5. Hadoop 2.0 and High Availability
What is Apache Hadoop? Apache Hadoop is an open-source software framework written in Java for distributed storage and distributed processing of very large data sets on computer clusters built from commodity hardware.
The Hadoop consists of a of storage Thecore coreofofApache Apache Hadoop consists a storage part, Distributed File File System part, known knownasasHadoop Hadoop Distributed System (HDFS), and a processing partpart called Map Map Reduce. (HDFS), and a processing called Reduce.
Hadoop splits files into large blocks and Hadoop splits files into large blocks and distributes them across nodes in in a cluster. distributes them across nodes a cluster.
Hadoop – Advantages and Disadvantages Advantages of Hadoop 1) Distribute data and computation. The computation local to data prevents the network overload. 2) Tasks are independent The task are independent so, • We can easy to handle partial failure. Here the entire nodes can fail and restart. • it avoids crawling horrors of failure and tolerant synchronous distributed systems. • Speculative execution to work around stragglers.
3) Linear scaling in the ideal case.It used to design for cheap, commodity hardware. 4) Simple programming model.The end-user programmer only writes map-reduce tasks. 5) HDFS store large amount of information 6) HDFS is simple and robust coherency model 7) That is it should store data reliably.

Disadvantages of Hadoop 1) Rough manner:- Hadoop Map-reduce and HDFS are rough in manner. Because the software under active development. 2) Programming model is very restrictive:- Lack of central data can be preventive. 3) Joins of multiple datasets are tricky and slow:- No indices! Often entire dataset gets copied in the process. 4) Cluster management is hard:- In the cluster, operations like debugging, distributing software, collection logs etc are too hard. 5) Still single master which requires care and may limit scaling 6) Managing job flow isn’t trivial when intermediate data should be kept 7) Optimal configuration of nodes not obvious.
What is Big Data Integration & Analytics Platform
The Big Data platform offers robust data integration in an open and scalable architecture leveraging technologies such as Talend, Hadoop, MongoDB to integrate and process the data.
