László Bodor updated HIVE-28789:
--------------------------------
Description:
The proposal aims to implement a mechanism in HS2 to retrieve metrics from Tez
sessions, with the actual implementation abstracted at the
TezSession/TezSessionState level.
An initial implementation in Hive could introduce a getMetrics abstraction with
a default implementation that fetches metrics from the most recent DagStatus
(obtained via dagClient). Later, a dedicated metrics endpoint can be introduced
for Tez AMs to further enhance this functionality.
Additionally, all metrics from Tez sessions can be aggregated and exposed in
HS2 for improved accessibility and convenience.

The proposal aims to implement a mechanism in HS2 to retrieve metrics from Tez
sessions. The actual implementation should be abstracted at the
TezSession/TezSessionState level.
An initial implementation in Hive could introduce a getMetrics abstraction
along with a default implementation that retrieves metrics from the most recent
DagStatus (obtained via dagClient). Later, a dedicated metrics endpoint can be
introduced for Tez AMs to enhance this functionality.
