Why does Cloudera need to create a Hadoop security component Sentry?1. Big Data Security System
To clarify this issue, we must start from four levels of the big data platform security system: Peripheral Security, data security, access security, and access behavior monitoring, as shown in;
Peripheral Security technology refers to the network security technology mentioned in the traditional sense, such as firewall and login authentication;

measures, the first time alarm. For the third and 4th, it is necessary to classify the anomalies.So a log collection system prototype sketched out: With the collection of logs (for distributed environment, the log distributed on each server), log statistics (the most statistics of the exception, often this is the hidden danger of the system), monitoring alarm (abnormal or abnormal accumulation to a certain amount of text messages or messages in the form of alarm) , and the visual interface for

The syntax is similar to some of the mainstream relational databases today. It is important to note that when the Sentry service is enabled, we must use the Beeline interface to perform hive queries, and the hive CLI does not support sentry.CREATE ROLE S
Today, the main two of the front-end statistical tools use, Sentry Matomo. The following are mainly statistical code access, so the premise is that you have set up the sentry and Matomo servers on your own serverSentry How to use statisticsSentry is a more complete error statistics log system, can be a pure front-end call, in the error log will be logged errors, user client information and user error steps
No matter what programming language you use, you will face the problem of how to handle the error log. Many programmers drift to the error log, until there is a failure to repent, if asked me how to do, I will recommend sentry!

The problem and Hdu 5093 the same as the portal. That is, the maximum matching number of the binary graph = minimum point set coverage. The problem requires a minimal number of robotic detention centers with important points, and obstructions that block the robot's Guard range.We might as well separate the rows and columns by the maximum number of guard ranges for the row and column, so that the maximum number of matches is obtained. Since the detention center has important points, so it can be
