Introduction to Namenode in Hadoop is like the heart of a human being, and it's important not to stop working. In the HADOOP1 era, there was only one namenode. If the Namenode data is missing or does not work, the entire cluster cannot be recovered. This is a single point in the Hadoop1 and a hadoop1 unreliable performance, as shown in Figure 1. 　　HADOOP2 solved the problem. The high reliability of HDFs in hadoop2.2.0 means that you can start 2 name ...

As early as the beginning of the 21st century, IBM had proposed that On Demand would change as needed, and HP also proposed Utility Computing utility calculations, while H3C proposed ...

Malware analysis, penetration testing, and computer forensics - GitHub hosts a host of compelling security tools that address the real needs of computing environments of all sizes. As the cornerstone of open source development, "all holes are superficial" has become a well-known principle or even a credo. As widely known as Linus's law, the theory that open code can improve the efficiency of project vulnerability detection is also widely accepted by IT professionals when discussing the security benefits of the open source model.

Fwsnort is a iptables rule set that is used to convert snort rules to an equivalent amount. By using the Iptables string-matching module, Fwsnort can detect many application-layer features in the snort rule. Fwsnort adds a hexadecimal string to the iptables option, which allows the snort rule to contain 16 characters without modifying the direct access to the Iptables rule set. In addition, Fwsnort accepts command-line arguments to limit the handling of any particular rule, dealing with even ...
