Configuration file

When the main() method of this class is used to start the program, the first argument is used as a path to the config file, which will be used to obtain configuration information. This file is a Properties file, so keys and values are separated by equals (=) and the key/value pairs are separated by new lines. The following is a general summary of keys used in the configuration file. For full details on this see the documentation in docs/index.html
  1. dataDir - The directory where the ZooKeeper data is stored.
  2. dataLogDir - The directory where the ZooKeeper transaction log is stored.
  3. clientPort - The port used to communicate with clients.
  4. tickTime - The duration of a tick in milliseconds. This is the basic unit of time in ZooKeeper.
  5. initLimit - The maximum number of ticks that a follower will wait to initially synchronize with a leader.
  6. syncLimit - The maximum number of ticks that a follower will wait for a message (including heartbeats) from the leader.
  7. server.id - This is the host:port[:port] that the server with the given id will use for the quorum protocol.
In addition to the config file. There is a file in the data directory called "myid" that contains the server id as an ASCII decimal value.
