Yes. Because if the query had just master, then the number of SQL procs
will be zero. Only the numOfTotalEspsUsed_ is maintained.
> RMS enhancements
> ----------------
>
> Key: TRAFODION-2420
> URL: https://issues.apache.org/jira/browse/TRAFODION-2420
> Project: Apache Trafodion
> Issue Type: Improvement
> Components: sql-general
> Affects Versions: 2.1-incubating
> Reporter: Selvaganesan Govindarajan
> Assignee: Selvaganesan Govindarajan
>
> Improve RMS to provide the following features/capabilities:
> 1. Currently RMS can list queries that consumed cpu time between two time
> points. However, the calls to storage engine like hbase, hdfs etc are
> blocking and these blocked APIs will not allow the Trafodion SQL engine
> scheduler to detect the cpu time spent during the time the call was blocked.
> Introduce a feature called SE offender (storage engine offender) to list the
> queries that are blocked in storage engine more than a certain duration.
> 2. Remove counters that are no longer updated or needed
