Subject [jira] [Created] (HDFS-5220) Expose group resolution time as metric
Date Tue, 17 Sep 2013 23:05:52 GMT
Rob Weltman created HDFS-5220:
---------------------------------

             Summary: Expose group resolution time as metric
                 Key: HDFS-5220
                 URL: https://issues.apache.org/jira/browse/HDFS-5220
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: namenode
            Reporter: Rob Weltman


It would help detect issues with authentication configuration and with overloading an authentication
source if the name node exposed the time taken for group resolution as a metric.
