Steve Loughran commented on HDFS-6226:
--------------------------------------
+1 for this; its a historical relic that actually loses data which different
appenders (e.g the json appender) to not see data.
This could also be a time to move to SLF4J for a logging api?
> Replace logging calls that use StringUtils.stringifyException to pass the
> exception instance to the log call.

> Key: HDFS-6226
> URL: https://issues.apache.org/jira/browse/HDFS-6226
> Project: Hadoop HDFS
> Issue Type: Bug
> Affects Versions: 3.0.0, 2.4.0
> Reporter: Chris Nauroth
>
> There are multiple places in the code that call
> {{StringUtils#stringifyException}} to capture the stack trace in a string and
> pass the result to a logging call. The resulting information is identical to
> passing the exception instance directly to the logger, i.e.
> {{LOG.error("fail", e)}}, so we can simplify the code.
