--------------------------------------------
Summary: Need to add new property for Ranger-Tagsync when enabling
federation for Namenode-HA via UI wizard
Key: AMBARI-23424
URL: https://issues.apache.org/jira/browse/AMBARI-23424
Project: Ambari
Issue Type: Bug
Components: ambari-web
Affects Versions: 2.7.0
Reporter: Aleksandr Kovalenko
Assignee: Aleksandr Kovalenko
Fix For: 2.7.0
Need to dynamically add properties in config-type {{ranger-tagsync-site}} from
UI for Federation wizard. This should be done when Atlas and Ranger-Tagsync
service is installed.
When federation is Enabled for HDFS, in this case for each name-service, we
will need to add a property in config-type {{ranger-tagsync-site}} using below
format:
{noformat}ranger.tagsync.atlas.hdfs.instance.<cluster-name>.nameservice.<name-service>.ranger.service=
<ranger service-name>{noformat}
The Ranger service name can be derived from logic as below:
If the value for property {{ranger.plugin.hdfs.service.name}} is default i.e.
{{{{repo_name}}}} then the value for above property will be in the format:
{noformat}<cluster-name>_hadoop_<name-service>{noformat}
for e.g if the cluster-name is {{testcl1}} and the name-services are {{ns1}} ,
{{ns2}} and the {{ranger.plugin.hdfs.service.name}} has value {{{{repo_name}}}}
then the property-value will be as below:
ranger.tagsync.atlas.hdfs.instance.testcl1.nameservice.ns1.ranger.service=testcl1_hadoop_ns1
ranger.tagsync.atlas.hdfs.instance.testcl1.nameservice.ns2.ranger.service=testcl1_hadoop_ns2
If the user has a custom-value for the property
{{ranger.plugin.hdfs.service.name}} i.e. not {{{{repo_name}}}}, then we will
need to use the value provided in for property
{{ranger.plugin.hdfs.service.name}} and use the format as
<custom-repo-name>_<name-service>.
for e.g if the cluster-name is {{testcl1}} and the name-services are {{ns1}} ,
{{ns2}} and the {{ranger.plugin.hdfs.service.name}} has value
{{hadoop_service}} then the property-value will be as below:
ranger.tagsync.atlas.hdfs.instance.testcl1.nameservice.ns1.ranger.service=hadoop_service_ns1
ranger.tagsync.atlas.hdfs.instance.testcl1.nameservice.ns2.ranger.service=hadoop_service_ns2
