How to choose the right version of hadoop

The installation and deployment of Hadoop environment is a problem that all beginners have to face when learning hadoop. For beginners, it will not be successful at one time, and it may even take several days to complete the deployment of hadoop runtime environment. So for beginners, the choice of hadoop version is still more important. In addition to the Apache version, there are many third-party versions of Hadoop. Although there are many versions, few of them can effectively solve the complex problems of hadoop deployment management like fast DKH.

The current hadoop distribution, in addition to the well-known open source version of Apache, there are Intel distribution, Cloudera distribution (CDH), Hortonworks distribution (HDP), MapR and so on. Domestic distributions such as Daxuai search DKH, Huawei distribution and so on. Both foreign third-party distributions and domestic distributions are basically based on Apache hadoop. As hadoop was born abroad, so the rules are made by foreign countries, domestic distribution hadoop of course not only big fast search, but dare to do the underlying development of hadoop only big fast search! It is precisely because of the technical advantages of Express that DKH is obviously different from other third-party distributions hadoop.

To sum up, the choice of hadoop version is diverse, in theory, you can choose Apache distribution, or foreign third-party distribution, of course, there are domestic distributions to choose from. However, for beginners, versions that require deployment in a complex environment do not seem to be suitable, and we should focus on hadoop application development rather than on the installation of the basic environment. It is our responsibility and obligation to do the underlying technology development of big data to solve the complex problem of basic environment installation.

If you want to recommend a hadoop version for entry-level hadoop beginners, you can use hadoop, the distribution of DKH. There are three different sub-versions of DKH Standard Edition: a stand-alone version for development and debugging; a learning version that supports three nodes; and a standard server version that supports more than five nodes. There are two sub-versions of the DKH- distributed SQL version: the learning version and the server version. Beginners can choose the learning version that supports three nodes in DKH Standard Edition.

DKH effectively integrates all the components of the whole HADOOP ecosystem, and deeply optimizes and recompiles into a complete and higher-performance big data general computing platform, realizing the organic coordination of various components. To put it simply, the deployment of the basic running environment has become extremely simple. Install it with one click and call it at any time!
