Apache ZooKeeper Admin Server API

The ZooKeeper Admin Server provides HTTP endpoints on port 8080 that expose the four-letter-word equivalent commands as REST endpoints for cluster monitoring, configuration, and diagnostics. Endpoints include /commands/conf (server configuration), /commands/stats (server statistics), /commands/mntr (monitoring metrics), /commands/envi (environment info), /commands/dump (session/ephemeral node dump), /commands/crst (connection reset), and /commands/leader (leader info for QuorumPeerMain).
