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
