Varun Saxena commented on YARN-5011:
------------------------------------
This patch is on top of YARN-4447.
This patch matches metric filters locally because flow run internal scanner
would run after records have been fetched from backend. And this coprocessor
performs summation operation before returning metric values for a flow run.
This would mean that metric filters wont work if passed as part of Get/Scan.
So these filters have to be matched locally and we also need to take care of
metrics to retrieve.
This patch does the following :
# Creates HBase qualifier filters for the metrics specified in metric filters
and metrics to retrieve. So we fetch only those metrics which need to be
matched against as part of metric filters. Or the ones which need to be
returned back in response.
# Metric filters are then applied locally to drop entities which do not match.
# We also remove from response, those metrics which have been fetched because
of metric filters but are not to be returned back in response due to metrics to
retrieve.
