Apache Software Foundation Apache ZooKeeper — Default Password
Default username and password for the Apache Software Foundation Apache ZooKeeper: (blank) / (blank). Learn how to log in and how to change the default credentials.
Apache ZooKeeper is a critical distributed coordination service used as the backbone of Kafka, Hadoop, HBase, Solr, and many other distributed systems. By default, ZooKeeper runs with NO authentication or access control enabled — all clients (including unauthenticated ones) can read, write, and delete any znode in the ZooKeeper tree. The admin HTTP interface (port 8080) and the client port (2181) are also open without authentication. ZooKeeper ACLs must be explicitly configured; they are not enabled by default in any standard distribution. This means any client with network access to port 2181 has full read/write/admin access to the coordination data of all connected distributed applications.

(blank / none) | (blank / none) | API | ZooKeeper 3.x (all versions) | No authentication by default. Connect via zkCli.sh -server <host>:2181. Full read/write access to all znodes without credentials. Admin HTTP server at port 8080 also unauthenticated. |
