ha.zookeeper.quorum is missing in core-site.xml (Adding new Services reverts
global and core-site configurations)
Key: AMBARI-6274
URL: https://issues.apache.org/jira/browse/AMBARI-6274
Project: Ambari
Issue Type: Bug
Components: client
Affects Versions: 1.5.0
Reporter: Andrii Tkach
Assignee: Andrii Tkach
Priority: Blocker
Fix For: 1.6.1
PROBLEM: Use Ambari 1.5.1, and upgrade HDP stack to 2.1 with Namenode HA
enable, at step 7 of
http://docs.hortonworks.com/HDPDocuments/Ambari-1.5.1.0/bk_upgrading_Ambari/content/ch02s03.html.
When try to restart HDFS, zkfc is not able to start due to ha.zookeeper.quorum
is missing in core-site.xml. And NN fails to become active. The error in
zkfc.log:
Unable to start failover controller. Unable to connect to ZooKeeper quorum at
klss20.test.com:2181,klss21.test.com:2181,klss22.test.com:2181. Please check
the configured value for ha.zookeeper.quorum and ensure that ZooKeeper is
running.
SUPPORT ANALYSIS:
The below setting should exists in core-site.xml:
<property>
<name>ha.zookeeper.quorum</name>
<value>klss20.test.com:2181,klss21.test.com:2181,klss22.test.com:2181</value>
</property>
