-------------------------------------------
Summary: YARN RM HA Mode Configurations Are Incorrect
Key: AMBARI-9950
URL: https://issues.apache.org/jira/browse/AMBARI-9950
Project: Ambari
Issue Type: Bug
Components: ambari-web
Affects Versions: 2.0.0
Reporter: Antonenko Alexander
Assignee: Antonenko Alexander
Priority: Critical
Fix For: 2.0.0
When enabling YARN RM HA mode, it doesn't appear as though we are creating the
additional {{yarn-site}} properties correctly. Consider that we do create the
following:
{noformat}
"yarn.resourcemanager.ha.automatic-failover.zk-base-path" :
"/yarn-leader-election",
"yarn.resourcemanager.ha.enabled" : "true",
"yarn.resourcemanager.ha.rm-ids" : "rm1,rm2",
"yarn.resourcemanager.hostname" : "c6402.ambari.apache.org",
"yarn.resourcemanager.hostname.rm1" : "c6402.ambari.apache.org",
"yarn.resourcemanager.hostname.rm2" : "c6403.ambari.apache.org",
"yarn.resourcemanager.webapp.address" : "c6402.ambari.apache.org:8088",
"yarn.resourcemanager.webapp.https.address" : "c6402.ambari.apache.org:8090”,
{noformat}
You can see that we have created aliases (rm1 and rm2) and created some dynamic
keys for these hosts, such as {{yarn.resourcemanager.hostname.rm1}}
However, the {{yarn-site}} documentation states that other properties, such as
the web address, need to also be specified in a similar manner. Otherwise, how
does YARN know which port to spin up the RM on each host?
{noformat:title=Missing Properties}
yarn.resourcemanager.webapp.address.rm1
yarn.resourcemanager.webapp.address.rm2
yarn.resourcemanager.webapp.https.address.rm1
yarn.resourcemanager.webapp.https.address.rm2
{noformat}
