Robert Surówka updated HIVE-2446:
---------------------------------
Attachment: HIVE-2446.1.patch
solution
> Introduction of client statistics publishers possibility
> --------------------------------------------------------
>
> Key: HIVE-2446
> URL: https://issues.apache.org/jira/browse/HIVE-2446
> Project: Hive
> Issue Type: Improvement
> Components: Clients, Statistics
> Reporter: Robert Surówka
> Priority: Minor
> Attachments: HIVE-2446.1.patch
>
> Original Estimate: 1h
> Remaining Estimate: 1h
>
> The purpose of this change is to allow publication or storage of counters
> while the job is running.
> Introduced two new variables to hive-default.xml and HiveConf.java:
> "hive.client.stats.publishers" and "hive.client.stats.counters". First one
> specifies classes names, whose instances will be executed by
> HadoopJobExecHelper.java (similarly as hooks are) in its method
> progress(ExecDriverTaskHandle): MapRedStats. Second one specifies list of
> counters that any client stat publishers should publish or stored. Details
> regarding format of this list is up to a specific deployment (it is up to
> client stats publishers to parse it), yet it is required to use display names
> of counter groups and counters.
> Added interface ClientStatsPublishers in org.apache.hadoop.hive.ql.stats
> package, that must be implemented by all stats publishers.
> Added code to progress(ExecDriverTaskHandle): MapRedStats from
> HadoopJobExecHelper.java that puts counters' values to a Java map and then
> executes registered client stats publishers giving them that map and running
> job id. Added two new methods to HadoopJobExecHelper:
> extractAllCounterValues(Counters) and getClientStatsPublishers() that are
> used by code from previous sentence.
> Made cosmetic changes in two other classes
