Hadoop is already very familiar to friends who work on the Internet. I believe there are a lot of people around us who are switching to hadoop development, and of course there will be a lot of beginners to hadoop. Hadoop development is too low-level, and the technology is much more difficult than we thought. For beginners, choosing a suitable version of hadoop means getting started faster!

Hadoop is a distributed system infrastructure developed by the Apache Foundation, and its core designs are HDFS and MapReduce. HDFS provides storage for massive data, while MapReduce provides computing for massive data. The rapid development of the domestic Internet has given birth to the rapid growth of big data technology, and the huge amount of data urgently needs a suitable processing method. Hadoop is in the tuyere, so it ushered in an explosive development. There are many domestic hadoop commercial distributions, it can be said that the foreign background occupies a dominant position, after all, hadoop was first put forward by foreign countries, and the corresponding rules of play have been formulated, and to a large extent, we can only passively accept it. Even so, we have seen some domestic distributions of hadoop. For example, Aliyun is doing big data, Huawei Cloud, Tencent Cloud and so on.

But the latest stable release of hadoop that you want to recommend for beginners to hadoop today is dkhadoop. Dkhadoop is a commercial release launched by Daxi, which integrates all the components of the entire hadoop ecosystem and makes in-depth optimization, and recompiles into a complete and higher-performance big data general computing platform, realizing the organic coordination of various components. Compared with the open source big data platform, Fast Hadoop has a great improvement in computing performance.

DKHadoop is also the one I'm currently using. The main current versions of Dkhadoop are: DKH standard version, DKH- distributed SQL version, DK.HADOOP distribution version. DKH Standard Edition has three different sub-versions: a stand-alone version for development and debugging; a learning version that supports three nodes; and a standard server version that supports more than 5 nodes. There are two sub-versions of DKH- distributed SQL version: learning version and server version.

For beginners to hadoop, it is recommended to choose a three-node one to meet their learning needs. You can download a standard version of the DKHadoop three-node study. The standard three-node version of DKHadoop can be downloaded for free, so it is more suitable for beginners, because there is no need to consider paying high fees! Friends who want the standard version of DKHadoop three nodes can find it themselves, of course, you can also leave me a message and ask me for it!
