---------------------------------
Summary: Counters and metrics
Key: HIVE-7438
URL: https://issues.apache.org/jira/browse/HIVE-7438
Project: Hive
Issue Type: Sub-task
Components: Spark
Reporter: Xuefu Zhang
Hive makes use of MapReduce counters for statistics and possibly for other
purposes. For Hive on Spark, we should achieve the same functionality using
Spark's accumulators.
Hive also collects metrics from MapReduce jobs traditionally. Spark job very
likely publishes a different set of metrics, which, if made available, would
help user to get insights into their spark jobs. Thus, we should obtain the
metrics and make them available as we do for MapReduce.
This task therefore includes 1. identify Hive's existing functionality w.r.t.
counters and metrics; 2. design and implement the same functionality in Spark.
Please refer to the design document for more information.
