hadoop - Can the same Zookeeper instance be used by number of services? -

does 1 zookeeper installation plenty used hadoop kafka , storm clusters? want deploy on 1 test environment , seek playing technologies, can utilize 1 zookeeper installation that? same znode dedicated number of services?

yes, can utilize single zookeeper installation back upwards more 1 cluster , indeed different types of clusters. has been case long time - here's link give-and-take on 2009: http://zookeeper-user.578899.n2.nabble.com/multiple-zk-clusters-or-a-single-shared-cluster-td3277547.html

for testing fine (and run on 1 zk server). production utilize though you'll want @ to the lowest degree 3 node cluster. , should think running off of single cluster.

the reason if run multiple hadoop, storm , kafka clusters off of single zk cluster, 1 set of servers becomes single point of failure of distributed systems. can beef zk setup more 3 servers (let's 7) can handle multiple failures, if accidentally bring zk downwards distributed environments come downwards too.

some argue improve off more isolation between systems. think varies utilize case i'd careful putting of eggs in 1 zk basket.
