Hello Folks! Welcome to Our Blog.

Apache Spark is an open-source, distributed processing system used for big data workloads.

It utilizes in-memory caching, and optimized query execution for fast analytic queries against data of any size. It provides development APIs in Java, Scala, Python and R, and supports code reuse across multiple workloads—batch processing, interactive queries, real-time analytics, machine learning, and graph processing.

Apache Spark has become one of the most popular big data distributed processing framework withmeetup members in The goal of Spark was to create a new framework, optimized for fast iterative processing like machine learning, and interactive data analysis, while retaining the scalability, and fault tolerance of Hadoop MapReduce. Spark can run standalone, on Apache Mesos, or most frequently on Apache Hadoop. Today, Spark has become one of the most active projects in the Hadoop ecosystem, with many organizations adopting Spark alongside Hadoop to process big data.

InSpark hadmeetup memberswhich represents a 5x growth over two years. It has received contribution by more than 1, developers from over organizations since Hadoop MapReduce is a programming model for processing big data sets with a parallel, distributed algorithm.

Developers can write massively parallelized operators, without having to worry about work distribution, and fault tolerance. However, a challenge to MapReduce is the sequential multi-step process it takes to run a job. Spark was created to address the limitations to MapReduce, by doing processing in-memory, reducing the number of steps in a job, and by reusing data across multiple parallel operations.

With Spark, only one-step is needed where data is read into memory, operations performed, and the results written back—resulting in a much faster execution.

Spark also reuses data by using an in-memory cache to greatly speed up machine learning algorithms that repeatedly call a function on the same dataset. Data re-use is accomplished through the creation of DataFrames, an abstraction over Resilient Distributed Dataset RDDwhich is a collection of objects that is cached in memory, and reused in multiple Spark operations. This dramatically lowers the latency making Spark multiple times faster than MapReduce, especially when doing machine learning, and interactive analytics.

Outside of the differences in the design of Spark and Hadoop MapReduce, many organizations have found these big data frameworks to be complimentary, using them together to solve a broader business challenge. Hadoop is an open source framework that has the Hadoop Distributed File System HDFS as storage, YARN as a way of managing computing resources used by different applications, and an implementation of the MapReduce programming model as an execution engine.

In a typical Hadoop implementation, different execution engines are also deployed such as Spark, Tez, and Presto.

Spark is an open source framework focused on interactive query, machine learning, and real-time workloads. It does not have its own storage system, but runs analytics on other storage systems like HDFS, or other popular stores like Amazon RedshiftAmazon S3Couchbase, Cassandra, and others.We put people and users at the heart of every decision that we make.

With intelligent flight control options, a mechanical gimbal, and a camera with incredible image quality, Spark empowers you to push your creative boundaries. With FaceAware, Spark lifts off from your hand by recognizing your face.

Take amazing aerial photos using just hand gestures, without a remote controller or mobile device. Intelligent Flight Modes and intuitive controls help you create cinematic aerial videos with just a few taps.

Quickly edit videos and share them straight to social media. Let Spark take professional shots for you. QuickShots help you shoot amazing footage with cinematic composition. In TapFly mode, just envision your shot and Spark captures it for you.

Tap your phone screen and Spark, using vision technology, flies in the direction of your tap or exactly where you tapped while actively sensing obstacles. Capture shot after shot with just your fingertips. With ActiveTrack, Spark automatically recognizes objects of different shapes and sizes then tracks them according to what they are and how fast they move. This makes tracking much easier and more reliable.

Deep learning gesture recognition allows you to take selfies with simple hand motions. Spark's 2-axis mechanical gimbal and UltraSmooth technology dramatically reduce shake and rolling shutter effect, keeping shots stable and detailed. All Spark images are consistently sharp and vivid with very little color aberration and distortion. Five elements are arranged into a single group that fit into a compressed frame. Larger pixels mean Spark is acutely sensitive to light and records colors precisely.

With its aerodynamic, lightweight, and slick design, Spark soars through the air with minimal wind resistance. The gimbal and camera are flush with the aircraft, significantly increasing stability. Powerful propulsion offers steady flight in strong winds at up to 31 mph 50 kph in Sport Mode. Innovative HD Wi-Fi technology allows for p real-time video transmission from up to 1. Even with all of Spark's intelligent features, flight time isn't compromised.

Fly for up to 16 minutes with a fully-charged battery, capturing more footage. Switch to Sport Mode and unleash Spark's speed potential. Sport Mode sets the gimbal mode to FPV by default, so the camera moves with you as you fly. Spark's FlightAutonomy system includes the main camera, vision positioning system VPS3D sensing system, dual-band GPS, high-precision inertial measurement unit, and 24 powerful computing cores. This allows Spark to hover accurately anywhere with VPS assistance at up to 98 ft 30 msense obstacles from up to 16 ft 5 m away, and land safely.

If the battery gets too low, connection is lost, or you hit the Return to Home RTH button, Spark flies back to the preset home point while sensing obstacles in its path. This provides the information needed to fly Spark safely and responsibly. Spark uses a high energy density LiPo battery for optimal performance.Battery not charging?
