Varun Saxena commented on YARN-5174:
------------------------------------
[~sjlee0], you had earlier said :
"I am not sure if we need to highlight the aggregation operation bit. "
The aggregation operation part is currently there in the document.
So what we need to decide upon is can some metrics at the level of task or
something semantically similar be posted by application directly without
aggregating them upto the level of application ? Or we assume they will
aggregate it by themselves (in which case this part can be removed). If we go
with latter, this can probably be explicitly stated.
Say, in case of Spark on YARN, multiple spark executors will be launched (with
each one executing multiple tasks). This will not be an immediate use case
though, if ever.

> One part that is missing in the documentation is the need to add
> {{hbase-site.xml}} on the client side (the client hadoop cluster). First, we
> need to arrive at the minimally required client setting to connect to the
> right hbase cluster. Then, we need to document it so that users know exactly
> what to do to configure the cluster to use the timeline service v.2.
