----------------------------------------------------
Summary: 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 Remove counters that are no longer updated or needed
