Hive Operator Counters
Jie Li 2013-02-06, 05:36
Hi all,

Does anyone notice that the operator counters are not properly
maintained? They are useful for understanding the query plan and
execution, e.g how many rows each operator is processing and
producing, and how much time each operator is spending.

NUM_INPUT_ROWS
NUM_OUTPUT_ROWS
TIME_TAKEN

They can be found in org.apache.hadoop.hive.ql.exec.Operator, but
since counterNameToEnum is never initialized, these counters are not
being calculated.

If this used to work and was broken somehow, I'll be glad to contribute:)
