|

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

# HOW TO EDIT THIS FILE:
|
||||
# The "handy ruler" below makes it easier to edit a package description.
|
||||
# Line up the first '|' above the ':' following the base package name, and
|
||||
# the '|' on the right side marks the last column you can put a character in.
|
||||
# You must make exactly 11 lines for the formatting to be correct. It's also
|
||||
# customary to leave one space after the ':' except on otherwise blank lines.
