Tsz Wo Nicholas Sze commented on HDFS-11559:
--------------------------------------------
There is a enableTrace feature with default true in MiniOzoneCluster.Builder to
make this happen. IMO, enabling trace for all the logs is never be useful
since it prints too many unrelated log messages as shown in the description.
