How To Hadoop

The great thing about cloud computing is that when you do large data processing, you don't have to buy a large number of server clusters in the past, and the rental server handles large numbers to make more use of control costs. As a heavyweight distributed processing open source framework, Hadoop has made a difference in the field of large data processing, and companies want to use Hadoop to plan their own future data processing blueprints. From EMC, Oracle to Microsoft, almost all High-tech vendors have announced their own large data strategy based on Hadoop over the past few months. Today Hadoop has become ...

The biggest effect of cloud computing is that it does not have to buy a large number of server clusters, or hire servers to handle large data, to reduce costs when doing large processing. As a heavyweight distributed processing open source framework, Hadoop is already known in large data-processing areas, and many companies want to use Hadoop to plan their own future dreams of data processing. From Oracle, EMC to Microsoft, almost all of the High-tech vendors have announced themselves in the past few months ...

In many people's minds, Hadoop seems to be synonymous with big data.　　    As you delve into big data and Hadoop, you have a deeper understanding of how Hadoop is just a storage tool for large data. But that's not necessarily a bad thing. Taking Hadoop as a cheap and efficient storage is just the perfect starting point for the next phase of Hadoop's evolution. The Hadoop 2.0, which is to be unveiled this summer, will make the information in the Data warehouse and the unstructured data pool unprecedented ...
