-------------------------------------
Summary: SHOW COMPACTIONS should include history and meta info
Key: HIVE-11994
URL: https://issues.apache.org/jira/browse/HIVE-11994
Project: Hive
Issue Type: Improvement
Components: Metastore, Transactions
Affects Versions: 1.0.0
Reporter: Eugene Koifman
Assignee: Eugene Koifman
Currently output of SHOW COMPACTIONS only has current information.
it would very useful if it could retain the data for a configurable period of
time after the Cleaner handles the entry. Perhaps the entry can go into 'h'
state for 'historical'.
Such historical data can be used to drive alert generating logic.
We can add a column with a JSON doc which can include various stats about the
job: number of delta files, size in MB, time taken. Also can be useful to
collect job properties from Hadoop, such as RAM used for example.
All of this can enhance the type/quality of alerts.
