[jira] [Commented] (YARN-1599) webUI rm.webapp.AppBlock should redirect to a history App page if and when available

["Gera Shegalov (JIRA)" <ji...@apache.org>]

Gera Shegalov commented on YARN-1599:
-------------------------------------

[~jlowe] thanks for pointing in the right direction. E.g., setting yarn.log.server.url to {code}http://${mapreduce.jobhistory.webapp.address}/jobhistory/logs{code} solves the problem on the pseudo-distributed cluster.

> When the log aggregation is enabled, and the application finishes, our users think that the AppMaster logs were lost because the link to the AM attempt logs are not updated and result in HTTP 404. Only tracking URL is updated. In order to have a smoother user experience, we propose to simply redirect to the new tracking URL when the page with invalid log links is accessed.
