Varun Saxena commented on YARN-5011:
------------------------------------
[~vrushalic], correct me if I am wrong. As I see in FlowRunCoprocessor, we are
working on cells after fetching them from the backend. This would be done after
HBase filters have been applied. Right ?
Column prefixes are not a problem here. We can easily decide metrics to
retrieve here.
There is an issue with metric filters though. We cannot apply
SingleColumnValueFilter because summation of metric values is done in
FlowScanner.
So I fetch all the columns required to match metric filters and then match them
locally. We do not bring all the data to the client side, just the required
one.
