Extra info for Apache ZooKeeper Essentials
Once a connection between the client and the ZooKeeper server has been established, a session is created between the client and the server, represented as a 64-bit number, which is assigned to the client. The concept of sessions is very important for the operation of ZooKeeper. A session is associated with every operation a client executes in a ZooKeeper service. Sessions play a very important role in ZooKeeper. For example, the whole notion of ephemeral znodes is based on the concept of sessions between the client and the ZooKeeper server.
On account of events such as session expiration and authentication failures, or if the application gracefully closes the connection using the library calls, the object's state moves to the CLOSED state.
Id=host:port:port format are the list of servers that constitute the quorum. id identifier is a number that is used for the server with a hostname in the quorum. In our example configuration, the zoo1 quorum member host is assigned an identifier 1. The identifier is needed to be specified in a file called myid in the data directory of that server. It's important that the myid file should consist of a single line that contains only the text (ASCII) of that server's ID. The id must be unique within the ensemble and should have a value between 1 and 255.
