Mohammad Arshad commented on ZOOKEEPER-4241:
--------------------------------------------
Have provided log4j1 based solution. Not sure whether it can be part of the
ZooKeeper as log4j1 based solutions are discouraged because log4j1 has reached
EOL.
[~pratikt] you can find the solution at PR
https://github.com/apache/zookeeper/pull/1637. See if it serves your propose.

> In our usecase of zookeeper, we want to change log level of zookeeper without
> restarting it.
> This will help us to trace issues without restarting zookeeper as some of the
> issues may not appear immediately after restart with debug log level enabled,
> and it may take longer to reproduce the issue after restart.
> Does such feature/API is already available in Apache Zookeeper?
> If it is not available then could you please consider this request to
> implement it?
> Please let us know if you need any further details from us.
