Akhil S Naik created AMBARI-24961:
-------------------------------------

             Summary: Ambari is unable to parse {{hostname}} in 
{hdfs-site/dfs.datanode.address} and is triggering alert for datanode process
                 Key: AMBARI-24961
                 URL: https://issues.apache.org/jira/browse/AMBARI-24961
             Project: Ambari
          Issue Type: Bug
          Components: ambari-agent
    Affects Versions: trunk, 2.6.2, 2.7.0
         Environment: Ambari is unable to parse {{hostname}} in 
{hdfs-site/dfs.datanode.address} and is triggering alert for datanode process

I changed the value of dfs.datanode.address in  Advanced hdfs configuration 
using ambari 

i set value to  {{hostname}}:50010 ( default value is 0.0.0.0:50010 ) 

Now after restart datanode is working fine and but ambari is triggering alert 
on datanode process with error : 

"Connection failed: [Errno -2] Name or service not known to {{hostname}}:50010" 

expected result : Ambari shouldnt trigger the alert and it should pass 
{{hostname}} correctly to localhost
