Examples of UpgradeCommand

com.cloud.agent.api.UpgradeCommand
UpgradeCommand is sent when the agent should update.
org.apache.hadoop.hdfs.server.protocol.UpgradeCommand
This as a generic distributed upgrade command. During the upgrade cluster components send upgrade commands to each other in order to obtain or share information with them. It is supposed that each upgrade defines specific upgrade command by deriving them from this class. The upgrade command contains version of the upgrade, which is verified on the receiving side and current status of the upgrade.

                    if (cmd instanceof CronCommand) {
                        final CronCommand watch = (CronCommand) cmd;
                        scheduleWatch(link, request, watch.getInterval() * 1000, watch.getInterval() * 1000);
                        answer = new Answer(cmd, true, null);
                    } else if (cmd instanceof UpgradeCommand) {
                        final UpgradeCommand upgrade = (UpgradeCommand) cmd;
                        answer = upgradeAgent(upgrade.getUpgradeUrl(), upgrade);
                    } else if (cmd instanceof ShutdownCommand) {
                        ShutdownCommand shutdown = (ShutdownCommand) cmd;
