---------------------------------
Summary: Displaying inconsistent CPU usage data with MR execution
engine
Key: HIVE-14215
URL: https://issues.apache.org/jira/browse/HIVE-14215
Project: Hive
Issue Type: Bug
Affects Versions: 2.2.0
Reporter: Peter Vary
Assignee: Peter Vary
Priority: Minor
If the MR task is finished after printing the cumulative CPU time then there is
the possibility to print inconsistent CPU usage information.
Correct one:
{noformat}
2016-07-12 11:31:42,961 Stage-3 map = 0%, reduce = 0%
2016-07-12 11:31:48,237 Stage-3 map = 100%, reduce = 0%, Cumulative CPU 2.5 sec
MapReduce Total cumulative CPU time: 2 seconds 500 msec
Ended Job = job_1468321038188_0003
MapReduce Jobs Launched:
Stage-Stage-3: Map: 1 Cumulative CPU: 2.5 sec HDFS Read: 5864 HDFS Write:
103 SUCCESS
Total MapReduce CPU Time Spent: 2 seconds 500 msec
{noformat}
One type of inconsistent data (easily reproducible one):
{noformat}
2016-07-12 11:39:00,540 Stage-3 map = 0%, reduce = 0%

MapReduce Jobs Launched:
Stage-Stage-3: Map: 1 Cumulative CPU: 2.51 sec HDFS Read: 5864 HDFS Write:
103 SUCCESS
Total MapReduce CPU Time Spent: 2 seconds 510 msec
