> ----------------------------------------------------------------------------------------

> Key: HADOOP-15942
> URL: https://issues.apache.org/jira/browse/HADOOP-15942
> Project: Hadoop Common
> Issue Type: Improvement
> Components: common
> Affects Versions: 3.1.0
> Reporter: Anuhan Torgonshar
> Priority: Major
> Labels: easyfix
>
> In *JMXJsonServlet.java* file, when invokes *MBeanServer.getAttribute()*
> method, many catch clauses followed, and each of them contains a log
> statement, most of them set the logging level to *ERROR*. However, when
> catches *RuntimeErrorException* in line 348 (r1839798), the logging level of
> log statement in this catch clause is *DEBUG*, the annotation indicates that
> an unexpected failure occured in getAttribute method before, so I think the
> logging level shuold be *ERROR* level too.
