runzhiwang updated HDDS-3978:
-----------------------------
Description:
We met dead lock related to log4j, the jstack information has been attached.
For the following two reasons, I want to switch log4j in ozone and ratis to
log4j2.
1. There are a lot of dead lock report in log4j:
https://stackoverflow.com/questions/3537870/production-settings-file-for-log4j/
2. And log4j2 is better than log4j.
https://stackoverflow.com/questions/30019585/log4j2-why-would-you-use-it-over-log4j
Besides log4j and log4j2 both exist in ozone, audit log use log4j2, and other
log use log4j, maybe it's time to unify them.
