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:

It should be noted that these two features are currently in the initial development stage. Despite their b
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.

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.

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 the "Virtual CPU", while the concept of virtual CPU is vague and ambiguous, and the community is trying to use the ECU concept in Amazon EC2 to regularize it, for specific reference:https://issues.apache.org/jira/browse/YARN-1024https://issues.apache.org
look at our infrastructure and our role:
Development Engineer
Test Engineer
Products
Other
Then we'll divide the boundaries of each role:
Development engineers should only focus on GIt code and JIRA bugs and new feature.
The test engineer only focuses on JIRA bugs and new feature tests.
Products and others are concerned only with JIR

In this article, I'd like to share some of the management tools and collaborative processes I've used in the AS7 development process, as well as some understanding of the open source community. The AS7 development process involves

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

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
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/jira/browse/HDFS/component/12313080
