The number of milliseconds of each tick

tickTime2000

The number of ticks that the initial

synchronization phase can take

initLimit10

The number of ticks that can pass between

sending a request and getting an acknowledgement

syncLimit5

the directory where the snapshot is stored.

do not use /tmp for storage, /tmp here is just

example sakes.

dataDir/opt/soft/zookeeper-3.4.6/zkData

the port at which the clients will connect

clientPort2181

the maximum number of client connections.

increase this if you need to handle more clients

#maxClientCnxns60 #

Be sure to read the maintenance section of the

administrator guide before turning on autopurge.

The number of snapshots to retain in dataDir

#autopurge.snapRetainCount3

Purge task interval in hours

Set to 0 to disable auto purge feature
