| .SH DESCRIPTION |
| |
| Apache ZooKeeper is a centralized service for maintaining configuration information, |
| naming, providing distributed synchronization, and providing group services. |
| All of these kinds of services are used in some form or another by distributed |
| applications. Each time they are implemented there is a lot of work that goes |
| into fixing the bugs and race conditions that are inevitable. Because of the |
| difficulty of implementing these kinds of services, applications initially |
| usually skimp on them, which make them brittle in the presence of change and |
| difficult to manage. Even when done correctly, different implementations of |
| these services lead to management complexity when the applications are deployed. |
| |
| For more information about ZooKeeper, see |
| .RS 0 |
| http://zookeeper.apache.org/. |
| |
| \fBzookeeper-server\fR starts/stops/etc... the ZooKeeper server. To |
| find the list of available commands and options for |
| \fBzookeeper-server\fR type: \fBzookeeper-server help\fR |
| |
| \fBzookeeper-server-initialize\fR initializes the ZooKeeper data |
| directory. This must be run after configuring the server, prior to |
| starting the service (the server will not start on an uninitialized |
| data directory). On a production system it is important to run |
| zookeeper-server-initialize under the same user id used for running |
| zookeeper-server (sudo -u zookeeper). To find the list of available |
| commands and options for \fBzookeeper-server-initialize\fR type: |
| \fBzookeeper-server-initialize -h\fR |
| |
| \fBzookeeper-client\fR starts the ZooKeeper client shell. To find the |
| list of available commands and options for \fBzookeeper-client\fR |
| type: \fBzookeeper-client help\fR |
