As the concept of large data has warmed up, Hadoop has been in the people's eye for some time as the most representative technology. The entire Hadoop ecosystem is developing at a rapid pace, with new features or new tools being generated almost every day. Although there are some minor changes, such as the more perfect support for scheduling in Oozie, or some still in development, such as support for NFS. There are also some very cool features, such as providing complete support for cpython in pig. But in my opinion, ...

Cloudera's idea of Hadoop as an enterprise data hub is bold, but the reality is quite different. 　　The Hadoop distance has a long way to go before other big data solutions are eclipsed. When you have a hammer big enough, everything looks like nails. This is one of the many potential problems that Hadoop 2.0 faces. For now, the biggest concern for developers and end-users is that Hadoop 2.0 has massively modified the framework for large data processing. Cloudera plans to build Hadoop 2.0 ...

3 o'clock in the morning, Arun C. Murthy was woken up by a phone call and the company asked him to deal with a software bug urgently. At the time, he was a Yahoo Ad app engineer, and the app was slow to run because a bunch of software code was poorly written when app enabled the open source digital platform Hadoop.     No one would have thought that this little bug, a few years later, contributed to the birth of the official Hadoop 2.0 and changed the fortunes of Hadoop. Although it was written by someone else, ...

Today, I attended 3 keynotes,42 sessions of 8, and a lot of vendors to discuss technology, is really a big bang day. Hadoop has been around for 7 years since its inception, and this year has seen many new changes: 1, Hadoop is recognized as a set of industry data standard open source software, in a distributed environment to provide a large number of data processing capacity (Gartner). Almost all major manufacturers revolve around Hadoop development tools, Open-source software, commercial tools, and technical services. This year, large IT companies, such as ...

The new Hadoop not only makes it possible to further stimulate the application of Hadoop, but it will also create a new method of data processing within Hadoop, which is impossible under previous architectural constraints. 　　In short, this is a good thing. 　　What has been limiting the development of Hadoop? More importantly, what is the future of Hadoop? Various criticisms of Hadoop revolve around its extended limitations, and the biggest problem here is its work. All the work in Hadoop is done by being called jobtr ...
