Review request for hive and Ning Zhang.
Summary
-------
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
This addresses bug HIVE-2446.
