Andrii Tkach created AMBARI-24585:
-------------------------------------
Summary:
'yarn.nodemanager.linux-container-executor.cgroups.hierarchy' is not equal to
the value of yarn_hierarchy in UI Deploy
Key: AMBARI-24585
URL: https://issues.apache.org/jira/browse/AMBARI-24585
Project: Ambari
Issue Type: Bug
Components: ambari-web
Affects Versions: 2.7.1
Reporter: Andrii Tkach
Assignee: Andrii Tkach
Fix For: 2.7.2
The property 'yarn.nodemanager.linux-container-executor.cgroups.hierarchy' does
not show up in the UI install wizard even when {{yarn_cgroups_enabled}} and
{{gpu_module_enabled}} are enabled in YARN configs. But this property is
available after deployment of the cluster.

When trying to set a value for the config
'yarn.nodemanager.linux-container-executor.cgroups.hierarchy', Stack advisor
displays the following:
{code}
yarn.nodemanager.linux-container-executor.cgroups.hierarchy and yarn_hierarchy
should always have same value
yarn.nodemanager.linux-container-executor.cgroups.hierarchy and yarn_hierarchy
should always have same value
Name of the Cgroups hierarchy under which all YARN jobs will be launched
{code}

>From the stack advisor description, looks like
>'yarn.nodemanager.linux-container-executor.cgroups.hierarchy' property needs
>to be same as yarn_hierarchy. As part of UI Deploy, the property
>{{yarn_hierarchy}} is set to
>{{hadoop-yarn-tmp-ctr-e138-1518143905142-461959-01-000002.hwx.site}}. But
>after deploy, the
>{{yarn.nodemanager.linux-container-executor.cgroups.hierarchy}} is set to
>{{/yarn}} and not the property set while UI Deploy. This is causing Deploy
>failures due to Nodemanagers not getting started. When this property is set
>correctly, Nodemanagers start successfully.
