I recently made an open source project disconf:distributed configuration Management Platform (distributed configuration Management Platform), simply, is the platform system that manages the configuration files for all business platform systems. For a more detailed introduction, see the Project homepage.The project is written in Java, Maven managed, then, naturally, the entire project should be exposed to the user using the Maven warehouse Pom method. So I've been tossing maven central Repository

ArticleDirectory Bugzilla Fogbugz JIRA Microsoft TFs Edgewall TRAC Issue Tracking System (ITS) is a system for software development. It allows you to track every problem process in software development until the problem is finally resolved. In its, a "problem" may be a bug, a function, or a test. These can be managed by its, and tracked by the owner or other management units. Its usually provides users with a path to repo

major features: namenode ha and wire-compatibility. After the above general explanation, you may understand that hadoop distinguishes versions based on major features. To sum up, the features used to differentiate hadoop versions include the following: (1) append supports file appending. If you want to use hbase, you need this feature. (2) raid introduces a verification code to reduce the number of data blocks while ensuring data reliability. Link: Https://issues.apache.org/

Project managers in software development usually need to weigh the key factors such as what kind of efficient tools to use and how to develop the project process schedule. The proper selection of agile tools can boost development projects and get twice the result with half the effort! 650) This. width = 650; "src =" http://cms.csdnimg.cn/article/201310/30/5270b285d859f.jpg "border =" 0 "style =" vertical-align: middle; Border: none; "alt =" 5270b285d859f.jpg "/> 1.

, datanode cache emerged (it is worth mentioning that the tachyon Storage System in the spark ecosystem is, is a memory system built on HDFS ). These two functions are the inevitable outcome of the development of a hadoop full-featured system. HDFS is no longer limited to storing some offline batch processing data, and it is also trying to store online data. For the design documents of these two functions, refer: Https://issues.apache.org/jira/browse/

Because Hadoop is still in its early stage of rapid development, and it is open-source, its version has been very messy. Some of the main features of Hadoop include:Append: Supports file appending. If you want to use HBase, you need this feature. RAID: to ensure data reliability, you can introduce verification codes to reduce the number of data blocks.

added compared to 0.23.x,2.x.After a rough explanation of the above, it may be understood that Hadoop distinguishes between versions with significant features, and concludes that the features used to differentiate Hadoop versions are as follows:(1) Append support file append function, if you want to use HBase, this feature is required.(2) RAID on the premise of ensuring that the data is reliable, by introducing a check code less data block number.

tasks on the same node, and Hadoop 1.0 uses only JVM-based resource isolation, which is very coarse grained.Although the resource management scenarios in Hadoop 2 seem perfect, there are a few issues that remain:(1) The total amount of resources is still statically configured and cannot be modified dynamically. This is already in the perfect, concrete can refer to:https://issues.apache.org/jira/browse/YARN-291(2) The CPU is set by the introduction of
