Overview
Copiar o linkLink copiado para a área de transferência!
This section covers two Zookeeper client concepts,
Retry and Retry interval and their properties. When an ensemble server is running, all containers that are part of fabric environment need to connect to this ensemble. The configadmin PID configuration for this process is io.fabric8.zookeeper and it is configured by the default fabric profile.
Note
The
etc/io.fabric8.zookeeper.cfg file must be removed.

The
zookeeper.url and zookeeper.password properties are configured by default. The other properties that can be configured in io.fabric8.zookeeper PID are:
| Property Name | Description | Default Value |
|---|---|---|
zookeeper.retry.max | Number of trials to establish the connection. | 3 |
zookeeper.retry.interval | Number of milliseconds to sleep between the connection attempts. | 500 |
zookeeper.connection.time.out or zookeeper.connection.timeout | Timeout while establishing the connection. | 15000 |
zookeeper.session.timeout | Once connection is established and the server session is created on server side. Client sends the session timeout and server checks the timeout. | 60000 |
To edit the properties, modify the default profile as:
profile-edit --pid io.fabric8.zookeeper/<propertyName>=<propertyValue> default [version]
profile-edit --pid io.fabric8.zookeeper/<propertyName>=<propertyValue> default [version]
