----------------------------------------
Summary: Non NameNode-HA properties still in hdfs-site.xml after
enabling HA (scripts refer to non-existent property values)
Key: AMBARI-15491
URL: https://issues.apache.org/jira/browse/AMBARI-15491
Project: Ambari
Issue Type: Bug
Reporter: Andrew Onischuk
Assignee: Andrew Onischuk
Fix For: 2.2.2
Attachments: AMBARI-15491.patch
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
