Tsz Wo (Nicholas), SZE commented on HADOOP-2851:
------------------------------------------------
Since it is showing stack trace, how about change the log level from debug to
trace?
> Bogus logging messages in Configration object constructors
> ----------------------------------------------------------
>
> Key: HADOOP-2851
> URL: https://issues.apache.org/jira/browse/HADOOP-2851
> Project: Hadoop Core
> Issue Type: Bug
> Components: conf
> Affects Versions: 0.16.0
> Reporter: Jingkei Ly
> Priority: Trivial
>
> The constructors for the Configuration object contains a superfluous logging
> message that logs an IOException whenever logging is enabled for the debug
> level. Basically both constructors have the statement:
> if (LOG.isDebugEnabled()) {
> LOG.debug(StringUtils.stringifyException(new IOException("config()")));
> }
> I can' t see any reason for it to be there and it just ends up leaving bogus
> IOExceptions in log files. It looks like its an old debug print statement
> which has accidentally been left in.
