We are using Zookeeper to implement consistent hashing, and need to be
able to add or remove hosts from the Zookeeper service without
interrupting its functionality.
According to http://zookeeper.wiki.sourceforge.net/ZooKeeperConfiguration
:
"Every machine that is part of the ZooKeeper service needs to know
about every other machine. So, we need to have a list of machines in
the configuration file."
Can we add a single Zookeeper server to the service with an expanded
host list without interrupting the proper functioning of the service?
The old servers will each have host list s_1, ..., s_k, and the new
server s_k+1 will have host list s_1, ..., s_k, s_k+1. Now we need to
restart the rest of the servers one by one from s_1 to s_k with the
new host list s_1, ..., s_k, s_k+1. Is this a violation of the service
specification?
Thanks,
Austin
