-----------------------------------------
Thanks [~jlowe], [~aw], [~templedf] and [~cheersyang] for sharing your views,
In our case we had a seperate OM console through which user managment was done
and cycle of user getting added and deleted is not deterministic and it would
not be ideal to track each user what was the id given earlier. And the job's
tasks were failing because of launching issues where ever any container had run
earlier for this recreated user.
And as mentioned by [~surendrasingh], fix was simple as NM user has the rights
to delete the folder and recreate with new ID fix was very simple if the folder
was not getting created we delete and recreate the folder during Application
initialization.
Though its not completely a YARN issue its easy to fix in YARN layer for this
scenario. Thoughts ?
