Fredorixo opened a new issue, #4679:
URL: https://github.com/apache/bookkeeper/issues/4679
**QUESTION**
The following logs appear when the autorecovery temporarily is unable to
access the bookies during pod restarts.
Can the logging for such a scenario be changed from ERROR to a WARN ? Also
is there a way auto-recovery can wait for some time period for the bookies to
get into running state before printing errors ?
```
