Transferred from: http://www.cnblogs.com/sharpxiajun/archive/2013/06/02/3113923.htmlZookeeper is a sub-project of Hadoop, and although it originates from Hadoop, I find that the zookeeper of developing a distributed framework out of the scope of Hadoop is growing. Today I want to talk about zookeeper, this article does not talk about how to use zookeeper, but

There are three ways to install zookeeper, Single-machine mode and cluster mode , and pseudo-cluster mode . Stand-alone mode: Zookeeper only run on one server, suitable for testing environment; Pseudo-cluster mode: To run multiple zookeeper instances on a single physical machine; Cluster mode: Zookeeper running on a cl

Literally, zookeeper represents a zoo keeper, which is a fascinating name, and we think of the Hadoop ecosystem, where many of the projects ' logos are used by animals, such as the image of the elephant in Hadoop, So we can guess that Zookeep is doing some management work on these animals.I. Zookeeper BASIC INTRODUCTION 1.1 The zoo also needs to be safe.Zookeeper is a sub-project under Hadoop that coordinat

Although zookeeper in the programming has many traps, the API is also very difficult to use, but the zookeeper service itself can say is very reliable, therefore appears on the net regarding the Movement dimension the article to be relatively few.

ZooKeeper is a top-of-the-range Apache project that provides distributed infrastructure services such as data publishing/subscription, load Balancing, naming services, distributed coordination/notification, and distributed locks, providing efficient, high-availability distributed coordination services for distribution applications. Thanks to its convenient usage, excellent performance and good stability, ZooKeeper
