-----------------------------

             Summary: NameNode Access Time Precision
                 Key: HADOOP-18171
                 URL: https://issues.apache.org/jira/browse/HADOOP-18171
             Project: Hadoop Common
          Issue Type: Improvement
         Environment: As of now we are on CDH version 6.3.4 and we are planning to upgrade it to CDP version 7.1.4. for that cloudera want us to disable namenode property dfs.access.time.precision by changing it's value to 0. Current value for this property is 1 hour. so my question is that how this value is impacting in current scenario? what is the effect of that and what will happen If I make it to zero.
