Junping Du commented on YARN-3223:
----------------------------------
Thanks [~brookz] for putting on a patch!
bq. Since this depends on YARN-3212, and the state transitions are added there,
this patch will not compile. This is just a review of the code.
Ok. So I will cancel the patch now. You may want to update the patch when
YARN-3212 get in finally.
Will provide some comments later.
