I setup a MapReduce job that scans HBase table with scan metrics enabled via Java API:
I expect HBase scan related counters to appear with current values in Hadoop web UI after job starts or in CLI after job ends alongside other counters such as CPU_MILLISECONDS. But no metrics were displayed. I can clearly see that scan is performed and mappers got non-zero inputs.
The JAR version is 1.2.0-cdh5.16.1.
