-------------------------------------
[~abmodi] I observed small correction needed in yarn-default.xml file. queue
capacity key name has 'writer' repeated twice.
{quote}{{<property>}}
{{ <description>The setting that decides the capacity of the queue to hold}}
{{ asynchronous timeline entities.</description>}}
{{ <name>yarn.timeline-service.-writer.-writer.async.queue.capacity</name>}}
{{ <value>100</value>}}

> For ATSv2 , if the backend is unreachable, the number/size of data held in
> timeline collector's memory increases significantly. This is not good for the
> NM memory.
> Filing jira to set a limit on how many/much should be retained by the
> timeline collector in memory in case the backend is not reachable.
