4lw (Apache ZooKeeper-specific)
Issue a ZooKeeper 4-letter-word command.
Use this command to access 4-letter-word commands, in a manner similar to issuing these commands via telnet.
By default 4-letter-word commands are disabled—you must enable them when configuring the ZooKeeper.
Example lines you can add to the zookeeper.properties file:
// Enable all 4lw commands 4lw.commands.whitelist=*
// Enable only ruok, stat, conf, isro 4lw.commands.whitelist=stat, ruok, conf, isro
Options
The following 4-letter-word commands are supported:
