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