---------------------------------------
Summary: Non NameNode-HA properties still in hdfs-site.xml causing
(at least) Balancer to fail
Key: AMBARI-13946
URL: https://issues.apache.org/jira/browse/AMBARI-13946
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: 2.1.2
Environment: CentOS6.7, HDP2.3-2950
Reporter: Benoit Perroud
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:
{code}
...
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 ...
{code}
These should be removed from the config.
Steps to reproduce: after turning on NameNode HA, {{grep
dfs.namenode.rpc-address /etc/hadoop/conf/hdfs-site.xml}} shouldn't return
anything
