-----------------------------------------
[~sseth] [~prasanth_j] fyi. I know next to nothing about how Hadoop metrics
work, so I'd be interested to look when I have time, but it won't be fast so if
you have a quick solution... ;)
> LLAP: output QueryFragmentCounters somewhere
> --------------------------------------------

> Key: HIVE-12558
> URL: https://issues.apache.org/jira/browse/HIVE-12558
> Project: Hive
> Issue Type: Bug
> Reporter: Sergey Shelukhin
>
> Right now, LLAP logs counters for every fragment; most of them are IO related
> and could be very useful, they also include table name so that things like
> cache hit ratio, etc., could be partitioned by table.
> We need to output them to some metric system (preserving the breakdown by
> table, possibly also adding query ID or even stage) so that they'd be usable
> without grep/sed/awk.
