runGet

public CommandResponse runGet(ZooKeeperServer zkServer,
                              Map<String,String> kwargs)

Description copied from interface: Command

Run this command for HTTP GET request. Commands take a ZooKeeperServer, String-valued keyword arguments and return a CommandResponse object containing any information constituting the response to the command. Commands are responsible for parsing keyword arguments and performing any error handling if necessary. Errors should be reported by setting the "error" entry of the returned map with an appropriate message rather than throwing an exception.

Specified by:

runGet in interface Command

Overrides:

runGet in class Commands.SrvrCommand

Parameters:

zkServer - ZooKeeper server

kwargs - keyword -> argument value mapping

Returns:

CommandResponse representing response to command containing at minimum: - "command" key containing the command's primary name - "error" key containing a String error message or null if no error
