Hi Ted,
thanks for the reply,

at the moment i'm hust wondering, why the client creates a zookeeper connection at all
all the client has to do, is to schedule a MR job, which is done by connecting to the jobtracker
and to provide all the needed stuff, config, some extra resources in the distributed cache
but what is the reasen for creating a zookeeper connection by the client?
