Cloudera recently released a news article on the Rhino project and data at-rest encryption in Apache Hadoop. The Rhino project is a project co-founded by Cloudera, Intel and Hadoop communities. This project aims to provide a comprehensive security framework for data protection. There are two aspects of data encryption in Hadoop: static data, persistent data on the hard disk, data transfer, transfer of data from one process or system to another process or system ...

VMware today unveiled the latest open source project--serengeti, which enables companies to quickly deploy, manage, and extend Apache Hadoop in virtual and cloud environments. In addition, VMware works with the Apache Hadoop community to develop extension capabilities that allow major components to "perceive virtualization" to support flexible scaling and further improve the performance of Hadoop in virtualized environments. Chen Zhijian, vice president of cloud applications services at VMware, said: "Gain competitive advantage by supporting companies to take full advantage of oversized data ...

1. The Hadoop version describes the configuration files that were previously (excluding this version) of the 0.20.2 version in Default.xml. 　　0.20.x version does not contain the Eclipse plug-in jar package, because of the different versions of Eclipse, so you need to compile the source code to generate the corresponding plug-ins. The 0.20.2--0.22.x version of the configuration file is focused on Conf/core-site.xml, Conf/hdfs-site.xml, and conf/mapr ...
