Joep Rottinghuis updated YARN-4786:
-----------------------------------
Labels: YARN-5355 (was: )
> Enhance hbase coprocessor aggregation operations:GLOBAL_MIN, LATEST_MIN etc
> and FINAL attributes
> ------------------------------------------------------------------------------------------------
>
> Key: YARN-4786
> URL: https://issues.apache.org/jira/browse/YARN-4786
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: timelineserver
> Reporter: Vrushali C
> Assignee: Vrushali C
> Labels: YARN-5355
>
> As part of YARN-4062, Joep and I had been discussing about min, max
> operations and the final attributes.
> YARN-4062 has GLOBAL_MIN, GLOBAL_MAX and SUM operations. It presently
> indicates SUM_FINAL for a cell that contains a metric that is the final value
> for the metric.
> We should enhance this such that the set of aggregation dimensions SUM, MIN,
> MAX, etc. are really set of a per-column level and shouldn't be passed from
> the client, but be instrumented by the ColumnHelper infrastructure instead.
> We should probably use a different tag value for that.
> Both aggregation dimension and this "FINAL_VALUE" or whatever abbreviation we
> use are needed to determine the right thing to do for compaction. Only one
> value needs to have this final value bit / tag set.
