Property

Description

nifi.zookeeper.connect.string

The Connect String that is needed to connect to Apache ZooKeeper. This is a comma-separated list of hostname:port pairs. For example, localhost:2181,localhost:2182,localhost:2183. This should contain a list of all ZooKeeper instances in the ZooKeeper quorum. This property must be specified to join a cluster and has no default value.

nifi.zookeeper.connect.timeout

How long to wait when connecting to ZooKeeper before considering the connection a failure. The default value is 3 secs.

nifi.zookeeper.session.timeout

How long to wait after losing a connection to ZooKeeper before the session is expired. The default value is 3 secs.

nifi.zookeeper.root.node

The root ZNode that should be used in ZooKeeper. ZooKeeper provides a directory-like structure for storing data. Each 'directory' in this structure is referred to as a ZNode. This denotes the root ZNode, or 'directory', that should be used for storing data. The default value is /root. This is important to set correctly, as which cluster the NiFi instance attempts to join is determined by which ZooKeeper instance it connects to and the ZooKeeper Root Node that is specified.
