Mohammad Kamrul Islam commented on HADOOP-11461:
------------------------------------------------

Looks like it is a known jersey bug for version 1.9.
Upgrading Jersey to 1.10 should resolve the issue. ( http://permalink.gmane.org/gmane.comp.java.jersey.user/10977)
Basically jersey patch downgraded this message level from "SEVERE" to "FINE".

Working on a patch to upgrade  the version.

If needed, an alternative approach may be to hide this "minor issue" by turning off this log. Related reference is in Hadoop KMS patch at https://issues.apache.org/jira/browse/HADOOP-10433.
We can test this by adding "log4j.logger.com.sun.jersey.server.wadl.generators.WadlGeneratorJAXBGrammarGenerator=OFF" into log4j.properties.
