Daniel Templeton commented on YARN-5600:
----------------------------------------
Thanks for the patch, [~miklos.szeg...@cloudera.com]. Some comments:
* It seems to me that you're doing extra work to keep the delete time as a
{{Date}}, not to mention adding potential time zone concerns. Millis since the
epoch may be simpler.
* Ignoring the {{IOException}} in
{{ResourceLocalizationService.submitDirForDeletion()}} seems bad. While you're
in there, it might be good to do something more useful.
* In your javadoc, the param text should start with a lower case letter, e.g.
{{DeletionService#deleteWithDelay()}}
* The {{DeletionService.scheduleFileDeletionTask()}} methods can and probably
should be private.
* In your tests, instead of sleeping and asserting, sleep for short periods in
a loop to minimize the test time.
* In {{TestContainerManager}} you have {code}- for (File f : new File[] {
containerDir, containerSysDir }) {
+ for (File f : new File[] {containerDir, containerSysDir }) {{code} You
may as well remove the trailing space as well.
* In {{TestContainerManager.verifyContainerDir()}}, your
if-if-else-else-if-else would be cleaner as if-elseif-elseif-else. Also, the
messages could be a little more descriptive so that someone reading it without
the source code has some clue what's happening. And I don't think we need the
exclamation points. :)
Otherwise, the general approach looks fine.

> To make debugging application launch failures simpler, I'd like to add a
> parameter to the CLC to allow an application owner to request delayed
> deletion of the application's launch artifacts.
> This JIRA solves largely the same problem as YARN-5599, but for cases where
> ATS is not in use, e.g. branch-2.
