unsupervised streaming

Hadoop Streaming provides a toolkit for MapReduce programming that enables Mapper and Reducer based on executable commands, scripting languages, or other programming languages to take advantage of the benefits and capabilities of the Hadoop parallel computing framework, To handle big data.All right, I admit the above is a copy. The following is the original dry goodsThe first deployment of the Hadoop environment, this can be referred to http://www.pow

About MapReduce and HDFs What is Hadoop? Google has proposed programming model MapReduce and Distributed file system for its business needs, and published relevant papers (available on Google Research's website: GFS, MapReduce). Doug Cutting and Mike Cafarella made their own implementations of the two papers when they developed the search engine Nutch, namely, MapReduce and HDFs, which together are Hadoop. The data flow of mapreduce, for example, was processed by mapper, then partition and sort

RTP Reference Document Rfc3550/rfc3551 Real-Time Transport Protocol) is a transport layer protocol for multimedia data streams on the Internet. The RTP protocol details the standard packet formats for transmitting audio and video on the Internet. RTP is often used in streaming media systems (with RTCP protocol), video conferencing and one-click push to talk systems (with H.323 or sip), making it the technical basis of the IP telephone industry. The RT

The simplest example of Flash-based streaming media: RTMP push and receipt (ActionScript) and rtmpactionscriptThis article records some Flash-based streaming media processing examples. The most common Streaming Media Protocol for Flash platforms is RTMP. Some RTMP players/streamer Based on C/C ++ recorded previously, but no RTMP player/streamer Based on the Flash

with The popularity of WEB application development, the need to play media ( video, audio ) in the browser is becoming more and more common; many enterprises are trying to add multimedia content to the website, the two most common ways :1. normal http file on demand, directly through the website front file upload upload file MP4 or FLV , save the path, the client through the open source Flash player or HTML5 The label goes to the playback server to return the video file for this path, which ma

BackgroundCompared with the traditional batch analysis platform such as Hadoop, the advantage of streaming analysis is real-time, that is, can be analyzed in the second-level delay.Of course, the disadvantage is that it is difficult to ensure strong consistency, that is, exactly-once semantics (in the premise of massive data, in order to guarantee the throughput, can not use similar transaction strong consistency scheme).General

This article records some examples of flash-based streaming media processing. The most common streaming media protocol for the Flash platform is rtmp. Some of the previously documented RTMP players/boosters are based on C + +, but no rtmp player/ejector based on ActionScript in Flash was recorded. In fact, the RTMP player/ejector based on Flash is a "regular" in rtmp technology. RTMP itself is designed to c

It converts the input stream into a dstream into an rdd, which can be handled using spark. It directly supports a variety of data sources: Kafka, Flume, Twitter, ZeroMQ, TCP sockets, etc., there are functions that can be manipulated:,,, map reduce joinwindow等。This article will connect spark
