---------------------------------------
[~talexey] Thanks for reporting the issue, [~zhangchen] Thanks for replay &
detailed clarification.
We also face the similar issue which exists for some time and recovered
automatically. But from the available INFO logs, we couldnt find which DN has
issue. We can enhance the logging for better traceability.
Can we print the log in INFO level? Sometimes issue not reproducible or
enabling DEBUG log lead to huge log. We can add an event based thread which
print the INFO log on node addition/deletion. What is your opinion?
