Review request for Ambari and Dmitro Lisnichenko.


Bugs: AMBARI-15491
    https://issues.apache.org/jira/browse/AMBARI-15491


Repository: ambari


Description
-------

This is a copy from AMBARI-13946, but I believe it has enough information

After enabling NameNode-HA, hdfs-site.xml does still contain non-HA
properties, including  
dfs.namenode.rpc-address  
dfs.namenode.http-address  
dfs.namenode.https-address  
This cause the balancer to fail with the following symptoms in Balancer:  
...

    
    
    
    15/11/18 15:48:30 INFO balancer.Balancer: namenodes  = [hdfs://daplab2, 
hdfs://daplab-rt-11.fri.lan:8020]
    ...

java.io.IOException: Another Balancer is running.. Exiting ...  
And ATS:

    
    
    
    _assert_valid
        self.target_status = self._get_file_status(target)
      File 
"/usr/lib/python2.6/site-packages/resource_management/libraries/providers/hdfs_resource.py",
 line 292, in _get_file_status
        list_status = self.util.run_command(target, 'GETFILESTATUS', 
method='GET', ignore_status_codes=['404'], assertable_result=False)
      File 
"/usr/lib/python2.6/site-packages/resource_management/libraries/providers/hdfs_resource.py",
 line 210, in run_command
        raise Fail(err_msg)
    resource_management.core.exceptions.Fail: Execution of 'curl -sS -L -w 
'%{http_code}' -X GET 
'http://pvvsccmn1-brn1:50070/webhdfs/v1/ats/done?op=GETFILESTATUS&user.name=hdfs''
 returned status_code=403. 
    {
      "RemoteException": {
        "exception": "StandbyException", 
        "javaClassName": "org.apache.hadoop.ipc.StandbyException", 
        "message": "Operation category READ is not supported in state standby"
      }
    }
    
    

These should be removed from the config.

Steps to reproduce:Enable namenode HA on Ambari 2.2

Expected behavior: after turning on NameNode HA, grep grep dfs.namenode.http-
address /etc/hadoop/conf/hdfs-site.xml shouldn't return anything
