Yiqun Lin commented on HDFS-12500:
----------------------------------
As ozone is very closest to merge to trunk, I'd like to make this JIRA done for
reducing the verbosity of logs that introduced in HDFS-12489.
Attach the patch. [~cheersyang], please have a review.

> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: ozone
> Reporter: Weiwei Yang
> Assignee: Yiqun Lin
> Priority: Minor
>
> Per discussion in HDFS-12489 to reduce the verbosity of logs when exception
> happens, lets add logger to {{Shell.java}} and move error stack traces to
> DEBUG level.
> And to track the execution time of oz commands, when logger is added, lets
> add a debug log to print the total time a command execution spent.
