Varun Saxena commented on YARN-4455:
------------------------------------
Thanks [~vrushalic] for the comments.
bq. If we know the metric name, we should set it in the scan and then use HBase
scan#setTimeRange
If we use setTimeRange or setTimestamp wouldn't it apply to all columns? I mean
if created time column has a timestamp which does not fall within range,
wouldn't that be excluded? IIUC, all cells have a timestamp.
bq. We should ensure we limit the number of records being returned. We should
also set the maxVersions to be 1.
Yes we currently have a metricsLimit query param which by default is 1. And we
use it to set max versions as you have suggested above.
