lincoln lee updated FLINK-24122:
--------------------------------
Fix Version/s: 1.20.0
> Add support to do clean in history server
> -----------------------------------------
>
> Key: FLINK-24122
> URL: https://issues.apache.org/jira/browse/FLINK-24122
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / REST
> Reporter: zlzhang0122
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.19.0, 1.20.0
>
>
> Now, the history server can clean history jobs by two means:
> # if users have configured
> {code:java}
> historyserver.archive.clean-expired-jobs: true{code}
> , then compare the files in hdfs over two clean interval and find the delete
> and clean the local cache file.
> # if users have configured the
> {code:java}
> historyserver.archive.retained-jobs:{code}
> a positive number, then clean the oldest files in hdfs and local.
> But the retained-jobs number is difficult to determine.
> For example, users may want to check the history jobs yesterday while many
> jobs failed today and exceed the retained-jobs number, then the history jobs
> of yesterday will be delete. So what if add a configuration which contain a
> retained-times that indicate the max time the history job retain?
> Also it can't clean the job history files which was no longer in hdfs but
> still cached in local filesystem and these files will store forever and can't
> be cleaned unless users manually do this. Maybe we can give a option and do
> this clean if the option says true.
