9.5. ZooKeeper Retry and Retry Interval


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.
The etc/io.fabric8.zookeeper.cfg file must be removed.

Properties for configuring the retry interval

The zookeeper.url and zookeeper.password properties are configured by default. The other properties that can be configured in io.fabric8.zookeeper PID are:
