----------------------------------
Summary: Automatically migrate old embedded zookeeper.properties
files to the new format
Key: NIFI-6624
URL: https://issues.apache.org/jira/browse/NIFI-6624
Project: Apache NiFi
Issue Type: Improvement
Components: Core Framework
Affects Versions: 1.9.2
Reporter: Nathan Gough
Assignee: Nathan Gough
Fix For: 1.10.0
The 3.5.x Zookeeper properties file has changed:
[https://zookeeper.apache.org/doc/r3.5.2-alpha/zookeeperReconfig.html#sc_reconfig_clientport]
As a result, the current embedded zookeeper bundled with NiFi will require a
minor change to the zookeeper.properties file. We could potentially do this
automatically by removing the clientPort line and appending the value to the
end of the server string/s.
The assumption here would be that the client port is currently configured the
same across all servers. If not, we would not be able to auto-migrate the
change, and we would need to fail the start and get the user to configure the
zookeeper.properties file correctly across all nodes.
