----------------------------------------
Summary: ATS heapsize cannot be changed in Ambari-2.2.1.1 or
greater post Ambari Server upgrade, even though the bug should be fixed
Key: AMBARI-15880
URL: https://issues.apache.org/jira/browse/AMBARI-15880
Project: Ambari
Issue Type: Bug
Reporter: Andrew Onischuk
Assignee: Andrew Onischuk
Fix For: 2.4.0
Attachments: AMBARI-15880.patch
yarn-env had an issue where ATS heapsize was not getting set correctly
This was fixed in Ambari-2.1.0 for HDP 2.2 and Ambari-2.2.1.1 for HDP 2.3/2.4.
However, "ambari-server upgrade" does not fix yarn-env, even if the user has
never touched it.
STR:
* Install a HDP 2.4.0 cluster with YARN using Ambari 2.2.1.0
* Confirm that yarn-env has **export
YARN_HISTORYSERVER_HEAPSIZE=`apptimelineserver_heapsize`** (this is incorrect)
* ambari-server stop
* Install ambari.repo for Ambari 2.2.1.1
* yum upgrade ambari-server
* ambari-server upgrade
* ambari-server start
Actual: yarn-env still has **export
YARN_HISTORYSERVER_HEAPSIZE=`apptimelineserver_heapsize`**
Expected: yarn-env has **export
YARN_TIMELINESERVER_HEAPSIZE=`apptimelineserver_heapsize`** instead
This means that changing "AppTimelineServer Java heap size" from the UI has no
effect on setting the actual heapsize for ATS.
