Advanced user of ZooKeeperIt is a very good tool/platform for managing a distributed system
it provides all the capability required like observe the servers and reelect masters when master node goes down
it also has persistent data service though its not a database it has data specific to zk, its a small storage
There is nothing specific
but its little difficult to debug, when we want to delete some nodes there are multiple places we need to delete
It is a very good platform if some one is trying to develop their own distributed server environments. It has multiple language support, primarily we used java. It is very handy and flexible enough to hook up custom logics.
we are not directly using zk, but used along with storm and kafka
In previous company we had a requirement to build a distributed server, where we wanted to put up some thing like master slave, Zk has all hook ups where nodes can be registered with callbacks when one node not up and zk gives call back to other nodes to kick in master election
