Nandakumar commented on HDDS-5803:
----------------------------------

Thanks [~zitadombi] & [~adoroszlai] for the detailed analysis.

We don't have to refactor and change {{hadoop.log.dir}} to {{ozone.log.dir}}. 
As you mentioned, it will be a big change and will also break backward 
compatibility.

In addition to the existing option, we can add support for {{ozone.log.dir}}
The order of precedence will be as follows
* {{ozone.log.dir}} JVM argument
* {{OZONE_LOG_DIR}} environment variable
* {{hadoop.log.dir}} JVM argument
* {{HADOOP_LOG_DIR}} (Deprecated)
* {{${OZONE_HOME}/logs}} (Fallback)

We can mark {{hadoop.log.dir}} as deprecated.



> Support "ozone.log.dir" property for configuring log location
