: Only extract and execute .rar files from trusted sources (like the official Apache ZooKeeper website ). Malicious actors sometimes use names of popular software to distribute malware.
: Ensuring that in a cluster of servers, one is designated as the "leader" to handle specific tasks while others remain "followers."
: Shell scripts and batch files to start, stop, and manage the server (e.g., zkServer.sh , zkCli.sh ).
: Allowing different processes to "lock" a resource so they don't overwrite each other's work.
: Keeping track of which servers are currently online and available within a large network. Important Considerations
: Java Archive (.jar) files containing the core logic and dependencies. docs/ : Documentation and help files for local reference. Key Use Cases
: For production environments, ZooKeeper is usually run in an "ensemble" (a cluster of an odd number of servers, like 3, 5, or 7) to ensure high availability.
: Storing and pushing configuration updates to all nodes in a cluster simultaneously.
