--------------------------------
Summary: RM Tracking Links for purged applications needs a
long-term solution
Key: YARN-304
URL: https://issues.apache.org/jira/browse/YARN-304
Project: Hadoop YARN
Issue Type: Improvement
Affects Versions: 0.23.5, 3.0.0
Reporter: Derek Dagit
This JIRA is intended to track a proper long-term fix for the issue described
in YARN-285.
The following is from the original description:
As applications complete, the RM tracks their IDs in a completed list. This
list is routinely truncated to limit the total number of application remembered
by the RM.
When a user clicks the History for a job, either the browser is redirected to
the application's tracking link obtained from the stored application instance.
But when the application has been purged from the RM, an error is displayed.
In very busy clusters the rate at which applications complete can cause
applications to be purged from the RM's internal list within hours, which
breaks the proxy URLs users have saved for their jobs.
We would like the RM to provide valid tracking links persist so that users are
not frustrated by broken links.
