> 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.
