After looking at the author's understanding of exactly once to disagree, so want to write this article, explain my spark streaming to ensure exactly once semantic understanding. the integrity of exactly once implementation First of all, a very important truth is: the whole system to the exactly once guarantee, never rely

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
