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.
