Subject [jira] [Updated] (HIVE-12558) LLAP: output QueryFragmentCounters somewhere
Date Tue, 01 Dec 2015 21:45:11 GMT

     [ https://issues.apache.org/jira/browse/HIVE-12558?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Sergey Shelukhin updated HIVE-12558:
------------------------------------
    Description: 
Right now, LLAP logs counters for every fragment; most of them are IO related and could be
very useful, they also include table names so that things like cache hit ratio, etc., could
be calculated for every table.
We need to output them to some metrics system (preserving the breakdown by table, possibly
also adding query ID or even stage) so that they'd be usable without grep/sed/awk.

be partitioned by table.
