MogileFS and Fastdfs's personal insights June 9, 2013 1 reviews MogileFS Fastdfs for two open source Distributed File system, are mainly used for Internet file sharing, upload, download and other functions, mainly for multi-upload and download, not often modified operations. The M and F deployment architectures are similar in that they are designed to avoid a single point problem in a cluster.MogileFS————————-official website : https://code.google.com/p/mogilefs/Basic Architec

BitTorrent protocol specification) Original BitTorrent protocol specification (English) BitTorrent is a file distribution protocol. It identifies content through URLs and can interact seamlessly with the Web. It is based on the HTTP protocol and has the following advantages: if multiple Downloaders concurrently download the same file, each downloader also uploads the file for other Downloaders at the same time, the file source supports a large number of users to download, but only increases the

., which are often collectively referred to as "Shuffle" or "mixed wash". The purpose of the shuffle is to comb, sort, and distribute the data to each reducer in a scientific way so that it can be efficiently calculated and processed (no wonder people say that this is where miracles happen, so there are so many flowers in it.) )If you are a Hadoop Daniel, look at this picture may soon be jumping out, no! There is a spill process ...Wait, about spill, I think just a realization of the details, in

SummaryThis paper studies the long-term tracking problem of unknown target in video stream. In the first frame, the tracking target is defined by the selected location and size. In each of the following frames, the tracking task is to determine the location and size of the target or to indicate that the target does not exist. We propose a novel tracking framework (TLD) that explicitly decomposes long-term tracking tasks into tracking, learning, and detection. The

oversight of two key functional modules HDFs, Map reduce. When job Tracker uses map reduce to monitor and schedule parallel processing of data, the name node is responsible for HDFS monitoring and scheduling. From the node responsible for the vast majority of the operation of the machine, to assume all data storage and instruction calculation of the drudgery. Each role that acts as a data node from a node is also charged with a daemon that communicat
