-------------------------------------------
Summary: HDFS should not need restart after adding second Hive
component
Key: AMBARI-9219
URL: https://issues.apache.org/jira/browse/AMBARI-9219
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
1) I added a second Hive Metastore, which also updates the proxyuser for hcat
to core-site
2) this requires a restart to NN and SNN, which is OK
3) then I went to add a second HiveServer2, that again updates the proxyuser,
just switches the order of the existing hosts in the property.
4) that property change should not have happened. There is no reason to force
another restart when the host list is not actually changing. So on property
update, we should not make the change if the host list is effectively the same.
See screen shot.
