    Description

      The metrics (renewalFailures and renewalFailuresTotal) in the following code snippet are not printable.

      UserGroupInformation.java
      metrics.renewalFailuresTotal.incr();
      final long tgtEndTime = tgt.getEndTime().getTime();
      LOG.warn("Exception encountered while running the renewal "
              + "command for {}. (TGT end time:{}, renewalFailures: {},"
              + "renewalFailuresTotal: {})", getUserName(), tgtEndTime,
          metrics.renewalFailures, metrics.renewalFailuresTotal, ie);
      

      The output of the code is like the following:

      2017-01-12 12:23:14,062 WARN security.UserGroupInformation (UserGroupInformation.java:run(1012)) - Exception encountered while running the renewal command for foo@EXAMPLE.COM.
