Suresh Srinivas commented on HDFS-4123:
---------------------------------------
This may not be a newbie. It should be done by someone with the background to
decide whether stack trace is intentionally not printed.
> HDFS logs should print stack trace and add a comment where it is
> intentionally not printed

> Key: HDFS-4123
> URL: https://issues.apache.org/jira/browse/HDFS-4123
> Project: Hadoop HDFS
> Issue Type: Improvement
> Reporter: Suresh Srinivas
> Priority: Minor
>
> Review the code and change the logs to print stack trace by changing the code
> from:
> {noformat}
> LOG.info("message" + exception)
> {noformat}
> to:
> {noformat}
> LOG.info("message", exception)
> {noformat}
> Where printing exception stack trace is avoided, add a comment to indicate
> that intent, to avoid someone changing it to print full stack trace.
