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

[~rlevas] ,

Could you please help me review this BUG.

i guess we should consider case of {{hostname}} while looking for localhost.

> 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
