--------------------------------------
Summary: Yarn/MR2 should handle a customized Zookeeper service
principal name
Key: AMBARI-22824
URL: https://issues.apache.org/jira/browse/AMBARI-22824
Project: Ambari
Issue Type: Improvement
Components: ambari-server
Affects Versions: 2.0.0
Reporter: Sandor Molnar
Assignee: Sandor Molnar
Fix For: 3.0.0
Yarn and MapReduce2 should handle a customized Zookeeper service principal name.
Currently this is not supported due to hardcoded and implicit values expecting
the Zookeeper service principal name to be {{zookeeper/_HOST}} as opposed to
something like {{zookeeper-mycluster/_HOST}}.
The following changes need to be made:
* common-services/YARN/2.1.0.2.0/package/scripts/params_linux.py must be
changed to not hardcode the Zookeeper principal name in
{code:java}
m_security_opts = format('-Dzookeeper.sasl.client=true
-Dzookeeper.sasl.client.username=zookeeper
-Djava.security.auth.login.config={yarn_jaas_file}
-Dzookeeper.sasl.clientconfig=Client')
{code}
* {{-Dzookeeper.sasl.client.username=<ZOOKEEPER_PRINCPAL_NAME>}} should be
added to {{YARN_OPTS}}
