------------------------------------------
Summary: Stackadvisor: incorrect recommendations when only one of
two dependencies was changed
Key: AMBARI-19236
URL: https://issues.apache.org/jira/browse/AMBARI-19236
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: 2.4.0
Reporter: Vitaly Brodetskyi
Assignee: Vitaly Brodetskyi
Priority: Critical
Fix For: 2.5.0
For example:
'mapreduce.map.memory.mb' depends on 'yarn.scheduler.maximum-allocation-mb' and
'yarn.scheduler.minimum-allocation-mb'.
*The case:*
'yarn.scheduler.minimum-allocation-mb' was changed, but
'yarn.scheduler.maximum-allocation-mb' not. In this case recommendations will
use provided value for the first property and recommended value for the second.
'mapreduce.map.memory.mb' will be recalculated incorrectly.
*Expected:*
Use the provided values for both properties.
