Recently, during the 240-site AD upgrade project, the contents of the Sysvol were not moved in half after the individual DC upgrade, and there was no movement for one weeks in a row, so I would like to share with you today how to deal with this problem.1.

The quality of a single SLR is better than that of a small DC. This is nonsense to take a picture of a single SLR.However, this is often not the case.It's not just a simple analysis of the advantages and disadvantages of SLR.It is self-evident that SLR is a concept. It is not a simple single machine, but a system. The SLR structure is only powerful so far. Its primary advantage is that it can support a powerful lens group. The second is the ability to

Scenario 1. What is Flume 1.1 backgroundFlume, as a real-time log collection system developed by Cloudera, has been recognized and widely used by the industry. The initial release version of Flume is now collectively known as Flume OG (original Generation), which belongs to Cloudera. But with the expansion of the FLume

http://blog.csdn.net/weijonathan/article/details/18301321Always want to contact storm real-time computing this piece of things, recently in the group to see a brother in Shanghai Luobao wrote Flume+kafka+storm real-time log flow system building documents, oneself also followed the whole, before Luobao some of the articles in some to note not mentioned, some of the wrong points later, In this way I will do the amendment, the content should say that mos

1) Introduction Flume is a distributed, reliable, and highly available system for aggregating massive logs. It supports customization of various data senders in the system for data collection. Flume also provides simple data processing, and write the capabilities of various data receivers (customizable. Design goals:(1) ReliabilityWhen a node fails, logs can be transferred to other nodes without being lost.

It's been a long time, but it's a very mature architecture.General data flow, from data acquisition-data access-loss calculation-output/Storage1). Data acquisitionresponsible for collecting data in real time from each node and choosing Cloudera Flume to realize2). Data Accessbecause the speed of data acquisition and the speed of data processing are not necessarily synchronous, a message middleware is added as a buffer, using Apache's Kafka3). Flow-bas

Flume is an excellent data acquisition component, some heavyweight, its nature is based on the query results of SQL statements assembled into OPENCSV format data, the default separator symbol is a comma (,), you can rewrite opencsv some classes to modify 1, download [Root@hadoop0 bigdata]# wget http://apache.fayea.com/flume/1.6.0/apache-flume-1.6.0-bin.tar.gz 2

Implementation Architecture A scenario implementation architecture is shown in the following illustration: Analysis of 3.1 producer layer Service assumptions within the PAAs platform are deployed within the Docker container, so to meet non-functional requirements, another process is responsible for collecting logs, thus not intruding into service frameworks and processes. Using flume ng for log collection, this open source component is very powerful

Simple method of 220V alternating current to low voltage DC resistance buck The conventional method of converting 220V alternating current to low-voltage DC is to use the transformer to buck and then rectify the filter, but when the product is limited by the factors such as volume and cost, the simplest and most practical method is to use capacitive buck mode.First, the circuit principleThe basic circuit of
