The 3 core components of the Apache Software Foundation’s Hadoop framework are:
1. MapReduce – A software programming model for processing large sets of data in parallel
2. HDFS – The Java-based distributed file system that can store all kinds of data without prior organization.
3. YARN – A resource management framework for scheduling and handling resource requests from distributed applications.
In this blog we’ll take a shallow dive into the Hadoop Distributed File System and its significance and contribution in providing…
Hadoop is an open-source software framework for storing and processing heavy data by distributing them on large clusters of dependable hardware. Essentially, the Hadoop framework was conceptualized to accomplish two tasks:
1. Massive data storage
2. Lightning fast processing
How was this framework named?
“Hadoop” was the name of a “Yellow Toy Elephant” owned by the son of one of its inventors.
Hadoop as a brand experienced euphoric and progressive success because of its ability to digest and adapt exponential change and encompass impacting sub-technologies within it, which eventually enhanced its purpose of existence.
With its ability…
In this age of Big Data, an organization’s ability to nimbly respond or adapt to variables affecting their operations — such as sales or supply chain issues, or even the weather — increasingly depends on how well it copes with the vast amounts of data and metadata flowing into its networks.
Splunk is a helpful tool for visualizing, monitoring, and analyzing all of that data and metadata.
Splunk is software for searching, monitoring, and analyzing machine-generated data from various sources through a Web-style interface. Machine data refers to…
There’s a persistent need for part-time database administrators, including such simple issues as covering for DBAs at night or during vacations or leave. Many companies maintain databases that do not require the services of a full-time DBA, but do need to be monitored and maintained. Datavail, the world’s largest firm devoted solely to remote database administration, has released a new whitepaper called 10 Reasons You Need Half a DBA, that analyzes many companies’ experiences with fractional services.
This is the second of two blog posts gleaning important…
