Store data in the cloud and learn the core concepts of buckets and objects with the Amazon S3 web service.
Learn what Hadoop is and how it can be used to store and process large amounts of data. Understand the basics of Hadoop, its components, and benefits.
Because of the massive volumes of logs, and their exponential growth, log storage is rapidly evolving. Historically, log aggregators would store logs in a centralized repository. Today, logs are increasingly stored on data lake technology, such as Amazon S3 or Hadoop. Data lakes can support unli...
HDFS expects that the cluster(s) will run on common hardware, i.e., regular machines rather than high-availability systems. Hadoop has the advantage of being able to be put on any common commodity hardware. To work with Hadoop, we don't require supercomputers, this results in significant co...
Scaling up and the limitations of parallel computing 纵向扩展和并行计算的局限性 Unlike distributed computing,parallel computingconsists of splitting a task into subtasks and assigning each to a different CPU (or different cores in a single CPU) on the same machine instead of different ones. For ...
Hadoop Distributed File System (HDFS) is a file system that manages large data sets that can run on commodity hardware. HDFS is the most popular data storage system for Hadoop and can be used to scale a single Apache Hadoop cluster to hundreds and even thousands of nodes. Because it efficie...
There are other staging models that HCI cannot easily incorporate, admitted Cisco's Agarwal -- for example, big data environments managed by dedicated operating systems such asHadoopandSpark. They have their own systems for redundancy, data protection, volume control, and fail-safes. You could en...
Present. The development of open source frameworks, such as Apache Hadoop and more recently, Apache Spark, was essential for the growth of big data because they make big data easier to work with and cheaper to store. In the years since then, the volume of big data has skyrocketed. Users ...

Hadoop YARN Project : This project involves working with the Hadoop YARN which is part of the Hadoop 2.0 ecosystem thus letting it decouple from the MapReduce application for computing of big data. This includes working on the Hadoop central resource manager. Some of the aspects of this project...
