Subject [Impala-ASF-CR] IMPALA-3342: Add thread counters to monitor plan fragment execution
Date Wed, 23 Nov 2016 00:56:48 GMT

Change subject: IMPALA-3342: Add thread counters to monitor plan fragment execution

IMPALA-3342: Add thread counters to monitor plan fragment execution

This change removes the use of total_cpu_timer which incorrectly
monitors the CPU time. Adding THREAD_COUNTERS to measure the user
and sys time in plan fragment execution. This also accounts for the
time spent in the hdfs/kudu scanner and in a blocking join.
