------------------------------------
Summary: Log a warning if multiple Compaction Worker versions are
running compactions
Key: HIVE-25642
URL: https://issues.apache.org/jira/browse/HIVE-25642
Project: Hive
Issue Type: Improvement
Components: Hive
Affects Versions: 4.0.0
Reporter: Csomor Viktor
Assignee: Csomor Viktor
Log a warning if multiple versions of a Compaction Workers are running.
The start time of the individual HMS services are not stored at the moment,
however this information could proved a good baseline of detecting multiple
Worker versions.
Due to the lack of this information we can check periodically in the past N
hours to detect the versions.
The N hours can be configured by
{{metastore.compactor.worker.detect_multiple_versions.threshold}} property.
This periodical check only make sense if the Compaction are enabled.
