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.

This script requires a 'zookeeper' user/group to exist before running.
|
||
|
|
The recommended UID/GID is 322. You can create these like so:
|
||
|
|
|
||
|
|
groupadd -g 322 zookeeper
|
||
|
|
useradd -u 322 -g 322 -c "Zookeeper user" -d /var/lib/zookeeper -s /bin/sh zookeeper
