-----------------------------------------
Summary: Ambari does not prompt History Server restart upon
modification in "yarn.log-aggregation.retain-seconds"
Key: AMBARI-24855
URL: https://issues.apache.org/jira/browse/AMBARI-24855
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: 2.6.1
Reporter: Krishnama Raju K
Currently aggregated log cleaner service runs in MR Job History Server as
"_AggregatedLogDeletionService_". Hence, any change in
"yarn.log-aggregation.retain-seconds" in yarn-site.xml should enforce a restart
of MR Job histotry server. However, we see only YARN service restarts to be
prompted. So, there should be another restart icon that should pop up for
MapReduce service for Job history server.
Ref: YARN Log aggregation behavior is explained

Steps to Reproduce
===============
# Make sure there are no stale configs (prompting restarts) in YARN or MR
service page
# In YARN config page change "yarn.log-aggregation.retain-seconds" from
default 30 days (in seconds) to any other value.
# Save and observe the restart icon appear on just YARN service in Ambari UI.
